Auther: Password Manager & 2FA

Auther is a private password manager and 2FA authenticator in one app. Keep your passwords, one-time codes (OTP), passkeys and payment cards in a single encrypted vault, unlock it with your fingerprint, and autofill logins in Chrome and your apps.

Secure by design
Your vault is encrypted on your device with AES-256. Your master password is protected with Argon2id or PBKDF2 key derivation and is never stored or transmitted. Optional Google Drive backup moves only ciphertext into your own Drive app data, so your secrets stay end-to-end encrypted and readable on your devices alone.

Everything in one vault
• Passwords and logins with usernames, URLs and notes
• Built-in 2FA authenticator with live TOTP codes
• Passkeys for passwordless sign-in on Android
• Payment cards with card autofill and save
• Folders and multiple vaults to stay organized

2FA authenticator built in
Scan a QR code or paste an otpauth link to add two-factor authentication. Your codes refresh on the standard 30-second cycle and sit right next to the login they protect. No separate authenticator app needed.

Autofill everywhere
Set Auther as your Autofill service and fill logins and cards across apps and Chrome. Can't find a match? Search your whole vault, fill the login and save the website to it in one tap, or add a new item without leaving the sign-in screen. New logins and cards you type are offered for saving automatically.

AccessibilityService API — optional Quick AutoFill
Auther uses Android's AccessibilityService API for Quick AutoFill when regular Autofill is unavailable. Only when you tap the Auther Quick AutoFill tile in Quick Settings, it reads the current app identity, browser website address and form field information to identify where to fill. After you unlock your vault and select an item, it fills your username, password or card details. It does not read existing text in form fields or continuously monitor your screen. Accessibility data is processed on your device for that request, not sent to servers or shared with third parties. Quick AutoFill requires your consent and can be disabled in Auther or Android Accessibility settings. Regular Autofill works without this permission.

Stays unlocked while you sign in
Unlock once and Auther stays ready for autofill. Your vault locks automatically after the timeout you choose once you leave the app, and items you mark as protected always ask for your master password.

Password and passphrase generator
Create strong, unique passwords or easy-to-type passphrases in a tap. Adjust length and character sets, and reuse from history when you need them.

Security dashboard
See where you're exposed. Auther flags weak and reused passwords completely offline. Pro adds breach checking powered by Have I Been Pwned, using k-anonymity so the password itself never leaves your device.

Unlock your way
• Fingerprint and face unlock
• Auto-lock on a timer, from immediately up to never
• Automatic clipboard clearing after you copy a secret

Import and export
Move in from 1Password, Bitwarden or a generic CSV in minutes. Export a backup whenever you want, with a clear plaintext warning so you stay in control.

Auther Pro
A low-cost subscription through Google Play, yearly or monthly, cancel anytime. Pro unlocks breach checking, multiple vaults, travel mode and more. Core password manager and 2FA features stay available without a subscription.

Privacy first
Auther never sees your data. No tracking, no ads, no selling your information. Only the encrypted vault can sync to your own Google Drive, and only a short hashed prefix is used for breach checks.

Requires Android 14 or later.
