- When a user opens the Yahoo Mail app they will be sent a push notification
- Clicking on this notification verifies their identity and unlocks their account
- Called Yahoo Account Key, the feature is available on iOS and Android
- And the firm said it will be rolling it out to other Yahoo apps later this year
Remembering countless passwords is the bane of many people's online lives, and Yahoo knows this.
Earlier this year it launched on-demand passwords for its Yahoo accounts and it has now extended this to its Mail app with a feature called Yahoo Account Key.
Now, when a user opens the app they will be sent a push notification.
Simply clicking this notification verifies who they are.
Typically push notifications appear along the top, or in the middle, of a mobile screen when they are received.
By using these notifications to let people sign into their Mail account, users don't have to leave the app to click the notification.
In a blog post announcing the update, Yahoo said: 'Passwords are usually simple to hack and easy to forget.
'Account Key streamlines the sign-in process with a secure, elegant and easy-to-use interface that makes access as easy as tapping a button.
'It's also more secure than a traditional password because once you activate Account Key - even if someone gets access to your account info - they can't sign in.'
The app update is Yahoo's latest move away from passwords.
In March, the firm added 'on-demand' passwords to Yahoo accounts.
Once enabled, users enter their username in the Yahoo login screen to receive a text message containing a password.
This password can only be used once and only works with the person's username. Once this password is entered into the login screen, the account is unlocked.
