The Firefox browser has a feature that will save your username and password of the corresponding website on your Android smartphone. The saved credentials are auto-filled when you visit the site, enabling easy sign-in with few taps and only accessible after successful authentication.
To get started with usernames and passwords:
1. You need to allow Firefox to Ask to Save credentials and enable the toggle switch for Autofill in the Firefox option.
2. The saved credentials will be available under the Saved Logins menu and only accessible after biometric or passcode authentication.
3. Under Saved Logins, you can Copy or Delete saved credentials.
When enabled, the saved logins are synced across the connected devices, and the credentials are auto-filled on other apps available on your device.
