Creating a great mobile app onboarding experience is more than just getting users to sign up quickly—it’s about balancing ease of use with robust security. As mobile apps become an essential part of our daily lives, they often handle sensitive information like personal details, financial data, or even biometric identifiers. This makes security a critical aspect of the onboarding process especially in a world where cyber threats are constantly evolving.
Therefore, app developers must ensure that users are protected from the moment they first engage with the app.
In this article, we will discuss the key security measures that are essential to any successful mobile app onboarding experience, explain how to balance security with usability, and highlight best practices that safeguard users without compromising their onboarding journey.
Let’s dive into the importance of secure onboarding and how it shapes both user trust and overall app success.
What is App Onboarding and Security?
App onboarding is the process that guides users through the initial setup of an app, helping them understand its features and get started easily. Think of it as the first impression your app makes—it’s about ensuring users feel comfortable and confident using it. A good onboarding experience not only introduces the app’s key functions but also simplifies account creation or login.
When it comes to security in onboarding, it’s all about protecting user data from the get-go. From sign-up methods to verification steps, security plays a critical role.
Trends like using mobile numbers with one-time passcodes (OTPs) instead of passwords are gaining traction because they’re more secure and user-friendly. For apps handling sensitive data, like financial or personal identification, biometric security—such as facial recognition or fingerprint scanning—offers an extra layer of protection.
In today's world, safeguarding users’ information during onboarding is more important than ever.
How to Secure Mobile App Onboarding Experiences
When it comes to onboarding security, there are several methods that ensure users can access an app safely while also protecting their sensitive information. Each method offers a unique level of convenience and security, and understanding these options is critical when designing the onboarding process for any app.
Here are four common onboarding security methods.
1. Cell Number with OTP (One-Time Passcode)
One of the most popular and convenient methods for onboarding security is using a cell phone number with a one-time passcode (OTP). This method requires users to input their mobile phone number during sign-up or login, after which they receive a unique code via SMS. They must then enter this code into the app to verify their identity and gain access.
The reason this method is becoming more favorable is due to its simplicity and security advantages. A user’s phone number is a stable piece of information—people rarely change their phone numbers, making it a reliable identifier. Also, users don’t have to deal with the hassle of creating and remembering complex passwords, which often end up being weak or reused across different platforms, creating a security risk.
From a security perspective, this approach significantly reduces the chances of accounts being hacked through stolen or compromised passwords. Since there is no password to steal, attackers have fewer ways to gain unauthorized access. Every time a user logs in, they are sent a new, single-use code, which means that even if a hacker intercepts one OTP, it cannot be used again. This dynamic approach makes it harder for malicious actors to exploit.
Another benefit is that this method eliminates the need for users to remember multiple passwords or worry about managing various email accounts, which can create friction during the onboarding process. Instead, they can rely on their mobile number, which they’re likely to have on hand at all times.
2. Biometric Verification
Biometric verification is another advanced method for securing the onboarding process, relying on unique physical characteristics like facial recognition, fingerprints, or voice recognition to verify a user’s identity. Unlike passwords or codes, biometrics are intrinsic to the individual, making this method both highly secure and convenient.
The key advantage of biometric verification is that it’s incredibly difficult to fake or steal. Hackers can potentially guess passwords or trick users into revealing sensitive information, but replicating someone’s fingerprint or face is much more challenging. This makes biometric verification one of the most secure options for onboarding, especially for applications that handle sensitive data, such as banking or identity management apps.
Biometric data is typically stored securely within the app or on the user’s device, and the verification process usually takes just a few seconds, allowing for a smooth user experience. Once a user verifies their identity with biometrics, the app can store that verification, meaning the user typically only has to complete the process once during onboarding.
However, because biometric data is so sensitive, it’s critical that developers implement this method carefully, ensuring that data is encrypted and protected at all times. Any breach of biometric information can have long-lasting security implications, so apps need to take extra precautions when using this method for onboarding.
3. Email in Place of Username
A more traditional but still effective method of onboarding security is using an email address in place of a username. In this scenario, the user’s email address serves as the unique identifier, and they are prompted to create a secure password that only they know. This approach remains widely used because it’s familiar to most users and provides a straightforward onboarding experience.
The strength of this method lies in its simplicity and the familiarity users already have with email-based logins. Nearly everyone has an email address, and most users are accustomed to verifying their accounts by clicking on confirmation links or entering verification codes sent to their inbox.
From a security standpoint, though, there are some risks involved, particularly around the strength of the password a user creates. If users select weak passwords or reuse the same password across multiple platforms, they become more vulnerable to attacks. This is why it’s important to implement strong password requirements, such as minimum character lengths, the inclusion of special characters, and prohibiting the use of easily guessed words.
Another potential issue with email-based onboarding is that email addresses are often targets for phishing scams. If a hacker gains access to a user’s email account, they can potentially reset passwords for other services, including the app itself, which creates a security risk.
Despite these risks, using email as the primary identifier still has its advantages. It allows for easier customer support, as admins can quickly locate user accounts based on their email addresses. It also gives users a clear way to recover their account if they forget their password, as password resets are generally sent via email.
4. Social Media Account Login
Social media account login, or social sign-in, allows users to log into an app using their credentials from a social media platform like Facebook, Google, or Twitter. This method streamlines the onboarding process by eliminating the need for users to create a new username and password. It’s convenient, as most people are already logged into their social media accounts, making it a quick, one-click solution.
However, while social sign-in offers ease of use, it comes with certain drawbacks. First, it creates data privacy concerns because users might unknowingly share more information with the app than they intend, as social platforms often have access to personal data like email addresses, friends, and location. Additionally, if a user opts to hide their email (as with Apple ID), it can make customer support more difficult, since the app’s administrators can’t easily verify or assist with account issues.
Another challenge is that if the user deactivates their social media account, they might lose access to the app unless they have set up another login method. Due to these concerns, we at AppIt generally advise steering away from social sign-in unless there’s a compelling reason to use it.
Security Measures in Mobile App Onboarding Examples
Let’s look at two real examples of app onboarding security—one where security failed and another where it succeeded. These examples highlight the importance of using the right method for the right context.
Example of Security Failure: Voice Hacking in Financial Services
A friend of mine experienced a serious security breach with her bank account, where a hacker was able to access her account by manipulating the voice verification system. The hacker knew the answers to common security questions, such as her mother’s maiden name, where she was born, and the last four digits of her social security number.
These are typical questions banks ask, and because the hacker had this information, they were able to impersonate her.
This failure occurred because traditional security questions, which are often reused across different services, were easily obtained by the hacker. The voice verification system in this case wasn’t robust enough to catch the impersonation, leading to the hacker gaining full access to her account.
Ultimately, her account had to be shut down to prevent further damage. This incident demonstrates how relying on outdated security measures, like security questions, is risky in today’s world of advanced hacking techniques.
Example of Security Success: Biometric Onboarding in My Colorado App
One successful example of app onboarding security is the My Colorado app, built by us at AppIt. This app is the first fully custom digital driver’s license in the US, and security was a top priority due to the sensitive personal information it handles.
For onboarding, we integrated biometric verification—specifically facial recognition—to ensure that the individual setting up the digital license is indeed who they say they are. Users must upload a photo of their government-issued ID and go through facial recognition to verify their identity. Once verified, they only need to go through this process once.
The security succeeds because biometric data is unique and incredibly difficult to replicate. Unlike traditional login methods such as passwords or security questions, biometric identifiers can’t be easily stolen or hacked. This ensures that only legitimate users can access their digital license, protecting personal data while still offering a seamless, user-friendly experience.
Balancing Security and the Onboarding User Experience
Balancing security with the onboarding user experience can be challenging, but it’s crucial for ensuring both protection and a smooth, engaging process for users. Here are three key factors to consider when finding this balance.
1. Understand the Purpose of the App
The level of security should always align with the app’s purpose. For example, if the app deals with sensitive information, such as financial data or personal identification (like the My Colorado app), a more rigorous onboarding process is necessary. This might include multi-step verification methods like biometrics or ID verification.
On the other hand, for apps with less critical data, simpler security measures like OTP login via mobile number might suffice.
By understanding what the app is meant to do and the risks involved, you can tailor the onboarding experience without adding unnecessary friction for the user.
2. Put Security First
While user experience is vital, security must come first—especially when personal data is involved. Weak onboarding processes that favor convenience over security can open the door to data breaches, identity theft, or other forms of hacking.
For instance, using passwords that are easy to remember but weak could compromise the app’s entire security.
Therefore, it’s essential to integrate strong methods like biometric authentication or OTP logins that strike a balance between ease and protection. Prioritize security features that users will perceive as safeguards, rather than obstacles, to their experience.
3. Implement Guided Onboarding
To balance a secure onboarding process with user satisfaction, it’s essential to guide users step-by-step through each stage of onboarding. This is especially important in apps that use more complex security methods, such as biometric or multi-factor authentication.
A guided onboarding process, with tooltips or walkthroughs, can help users understand why each security step is necessary and how it benefits them. Clear, concise instructions and explanations about the reasons behind certain security measures will make users feel more comfortable, ensuring that they are more likely to complete the onboarding process without frustration.
By carefully integrating these factors, you can ensure strong security while providing a positive and frictionless user experience.
Final Thoughts on Creating a Secure Onboarding Process
