OM Authenticator (TOTP) de OM Studio

OM Authenticator generates time-based one-time passwords locally in Firefox.

Features:

• RFC 6238 TOTP with SHA-1, SHA-256 and SHA-512;
• 6- and 8-digit codes and custom periods;
• manual service entry;
• standard otpauth:// QR image import;
• import of the current known Google Authenticator migration format, including multi-QR batches;
• encrypted local vault;
• encrypted password-protected backup and recovery;
• search, editing, deletion and manual ordering;
• six interface languages and system, light and dark themes;
• keyboard and screen-reader accessibility.

The extension works offline. It does not use Firefox Sync, analytics, telemetry, remote code or external services. Private Browsing and active-tab capture are intentionally unsupported.

The unlocked Firefox profile is treated as trusted. There is no separate local master password. Create an encrypted backup so your saved services can be restored if Firefox profile data is cleared, damaged or removed.
