Manage your information smarter!

Try managing it right now with "What Was My Password?" [Accessibility Service Usage Guide]

'What Was My Password?' optionally uses the Accessibility Service for its password autocomplete feature.

• Purpose: It detects ID/password input fields on login screens in other apps or browsers and automatically fills in saved accounts when the user manually selects them. (This is an auxiliary feature for screens where the Android Autocomplete framework is not supported.)

• Activation: Users must manually enable this feature in system settings after agreeing to the in-app instructions, and it can be turned off at any time.

• Data: It does not collect, store, or transmit screen content or personal information externally. Field detection and input are all processed within the device.
No more memorizing!
