4OTP

Purpose: 4OTP generates six-digit time-based one-time passwords that change every 30 seconds to help secure online accounts.
Code management: The app supports code search, pinning, renaming, automatic icons, next-code display, and recovery of deleted codes.
Import and export: Users can import codes from Google Authenticator and export codes to Google Authenticator or compatible apps.
Encrypted backups: Users can export codes in a fully encrypted backup file and restore that file on another device.
Encryption: The maker says 4OTP encrypts data on the device using a password-derived key and AES-GCM, and uses end-to-end encryption for Sync.
Password recovery limit: The maker says it cannot decrypt codes without the password, so losing the password means losing access to the codes.
Sync history: Sync records the last 50 changes and lets users revert their devices to a previous code-list version.
Device limit: The Sync plan supports up to 50 devices.
Sharing and access control: Users can create separate Sync access keys for devices or other people and delete keys to revoke access.
Offline use: The apps can work offline without an account; an account is used for the optional Sync service.
Supported versions: The download page lists Windows 10 or newer, macOS 10.13 or newer, Android 12 or newer, and iOS 16 or newer.
Languages: The apps include 22 languages, with device-language detection and an option to choose a language in settings.
Support: The maker directs users to email [email protected] and says it will respond as quickly as possible.
Maker and Linux: The About page identifies Weeblr as the maker and says Linux support is a goal, but is not available currently.
Price from: $3/mo
