Enter your username and password in any app, in any context, in any text field. Tiny Password for Android features its own pattern-locked Input Method Editor (IME) aka keyboard. No need to open or switch between apps to retrieve your credentials using the clipboard, tap once for the menu and select the field you would like to enter. Tiny Password for Android uses the native Android pattern lock for security. Forget tediously typing a master password with the virtual keyboard just to look at your passwords. Login quickly and get to your passwords effortlessly. Import or export of comma separated value (CSV) files is also supported, making password entry a lot easier. Tiny Password for Android also imports CSVs from KeePass 1.x, LastPass, and plain text files from 1Password.
