About
This app generates the six-digit codes you need when a service asks for a second step at sign-in. Scan a QR code once, and the code is there whenever you come back.
Everything happens on your device. There is no account to create and nothing to sign up for.
What it does
Generates time-based one-time codes (TOTP) that refresh every thirty seconds. Works with any service that supports authenticator apps — email providers, social networks, cloud storage, developer tools, crypto platforms, work accounts and more.
Adding an account takes a few seconds: scan the QR code the service shows you, or type in the setup key by hand if there is no code to scan.
Codes work without an internet connection. They are calculated on your phone from the time and the key, so a weak signal or no signal at all makes no difference.
You can rename accounts, reorder the list, and remove what you no longer use. If you would rather not leave your codes open on the screen, the app can be locked with Face ID, Touch ID or a passcode.
