About

OTP Keyboard

Features
Read full description

OTP Keyboard generates standard TOTP/HOTP verification codes on your device and puts them right where you need them: on your keyboard and in AutoFill. NO APP SWITCHING • A dedicated keyboard shows your codes right below any login field — tap once to type them • Verification-code AutoFill fills codes without opening the app • One-tap copy, and copied codes clear from the clipboard after 30 seconds QUICK SETUP • Scan a setup QR code with the camera, read one from a photo, or enter the key manually • Works with GitHub, Google, AWS, Notion and every service that supports authenticator apps (TOTP/HOTP, SHA-1/256/512, 6 or 8 digits) PRIVATE BY DESIGN • Secret keys are stored in iCloud Keychain and sync end-to-end encrypted across your devices • Codes are generated on device — nothing is sent to our servers, and there are no analytics • Face ID lock, hidden App Switcher preview, and encrypted file backups • The keyboard never logs what you type; without Full Access it still works as a number pad SIMPLE TO MANAGE • Drag cards to reorder — the keyboard list follows your order • Search, edit, and organize your accounts OTP Keyboard is built for one thing: getting your two-factor code into the field in front of you, faster.
