Google Simplifies App Sign-In by Eliminating OTP and Link Frustrations

If you have ever registered for an application only to waste five minutes searching for a six-digit code hidden in your email, you understand how tedious this process can be. I particularly dislike the magic sign-up links that websites send, as they often stop functioning if my default browser is not Google Chrome.

Fortunately, Google is addressing this issue with a new verified email credential for Android, offering a truly clever solution.

What is wrong with OTPs?

The standard OTP has long been the foundation of email verification, yet it presents significant challenges. You must exit the app, open your inbox, locate the email, copy the code, and return to the app.

This lengthy procedure frustrates both users and app developers. The excessive number of steps can cause users to abandon the sign-up process, resulting in lost potential users before they even experience the app.

iOS resolved this problem by enabling users to sign in via Apple account. Recently, it also introduced a feature to autofill OTPs from emails, similar to how Android supports OTP autofill from messages.

Now, Google is developing a seamless signup process that eliminates the need for users to switch between apps.

How does the new system work?

Google now issues a cryptographically verified email credential directly to Android devices through the Credential Manager API. When an app needs to confirm your email, it can retrieve that credential directly using the Credential Manager API.

A small prompt appears on screen showing what information is being requested. You tap to confirm, and the app gets your verified email. No switching apps, no codes, no delay.

Google recommends pairing this with passkey creation, so the first sign-up becomes the last time a user has to do anything manual.

The same can also be used for account recovery and re-authentication of sensitive actions, including setting changes, updating profile details, and more.

The best part is that the new feature supports Android 9 and later devices, so you don’t need the best new Android smartphones to enjoy this quality-of-life improvement.

Are there any restrictions?

There are a few restrictions. The feature currently works only with regular consumer Google Accounts, not Workspace accounts. It also only works with Gmail accounts, and not with third-party email accounts that you might have used to create your Google account.
