About this Tool

Authenticator ·

iOS two-factor authentication app that generates TOTP codes for securing online accounts, with iCloud Keychain backup.

Authenticator · is a two-factor authentication app for iOS that generates time-based one-time passwords (TOTP) to secure your online accounts. It stores your 2FA codes locally and displays them with a live countdown timer so you always know when a code expires.

The app supports QR code scanning to add new accounts quickly and keeps all tokens in an encrypted local vault. Optional iCloud Keychain sync lets you restore codes when switching devices without exposing them to third-party servers.

Designed for developers and security-conscious users who manage multiple services, it provides a clean, minimal interface that surfaces the right code without friction. There is no AI component — it is a deterministic TOTP utility built on the RFC 6238 standard.
