What is biometric login?

Biometric login allows users to authenticate using unique physical characteristics, typically:

  • Face ID (facial recognition)
  • Touch ID (fingerprint recognition)

Instead of entering a username and password, users verify their identity directly on their device. This makes the login process both faster and more secure. Biometric data is never stored within the app itself but is securely managed by the device using Apple's and Android's built-in security frameworks.

Why is biometric login important?

Today, most users unlock their phones with their face or fingerprint - and they expect the same seamless experience when using an app.

If logging in requires long passwords or repeated password resets, users are more likely to abandon the app before they even get started. Biometric login provides both speed and security. Users can access the app in seconds while sensitive information remains protected by the device's built-in security features.

The result is a smoother user experience, fewer barriers to returning to your app and a solution that meets the expectations users already have of modern mobile applications.

Why choose biometric login for your app?

A seamless login experience is essential for both user satisfaction and retention. Biometric login offers benefits for both your business and your users:

  • Faster access - users can sign in within seconds
  • Enhanced security - identity is verified using the device’s secure biometric authentication
  • Fewer forgotten passwords - reducing the need for password resets
  • Improved user retention - fewer users abandon the login process
  • A modern user experience - Face ID and Touch ID have become standard expectations in many apps

When does biometric login create value?

Biometric login is particularly valuable for apps where security and usability need to go hand in hand.

Employee and intranet apps

Give employees fast and secure access to internal systems without compromising security. When employees log in several times a day, biometric authentication saves both time and frustration.

Membership and customer apps

If your app contains personal information, membership benefits, purchase history or payment details, biometric login provides an extra layer of security while giving users fast access.

SaaS platforms

Professional users often access SaaS applications multiple times a day. Biometric login speeds up access, allowing users to focus on their work instead of logging in.

Financial services

Banking, insurance and payment apps demand a high level of security. Face ID and Touch ID have become an expected standard that builds trust with users.

Healthcare and patient apps

When an app contains personal health information or sensitive data, biometric login provides secure yet convenient access without requiring users to remember complex passwords.

Education and learning platforms

Students and learners can quickly access courses and learning materials between classes and activities without resetting passwords or spending time logging in.

Social sign-in - make onboarding even easier

Biometric login makes it easy for existing users to return to your app. Social sign-in makes it easy for new users to get started.

With social sign-in, users can create an account or sign in using an existing account from providers such as:

  • Google
  • Apple
  • Facebook
  • Microsoft
  • Other identity providers

Instead of filling out lengthy registration forms and creating another password, users can get started in just a few taps. This reduces friction during onboarding and increases the likelihood that users complete the registration process.

When does social sign-in make sense?

Social sign-in is especially effective when fast onboarding is essential.

New users

The easier it is to create an account, the more users complete registration and become active users.

E-commerce and booking apps

When users want to complete a purchase or booking quickly, login should never become an obstacle.

Community and membership apps

Make it easy for users to join your community, become members and access relevant content without lengthy registration processes.

Combine biometric login and social sign-in

The two features complement each other perfectly.

Social sign-in provides a fast and simple account creation process for new users, while biometric login makes returning to the app quick and secure.

The result is a seamless login experience with minimal friction throughout the entire user journey - from the very first visit to everyday use.

Security and usability in perfect balance

Login is the first interaction users have with your app. When the experience is fast, secure and effortless, it becomes easier to build trust and encourage users to return.

With starti.app, you can combine biometric login and social sign-in in one integrated solution.
