AuthGeek: a desktop TOTP authenticator with an Argon2 vault and no cloud sync

Description and use

AuthGeek is a local desktop TOTP/HOTP authenticator that uses Argon2id encryption, QR scanning, and encrypted backups, eliminating cloud sync and external accounts.

Problem

Users need a local TOTP/HOTP authenticator that does not require cloud sync or external accounts, to keep second-factor secrets under their own control.

Outcome

AuthGeek enables users to manage TOTP/HOTP secrets locally without cloud sync, providing privacy and control while maintaining usability via QR scanning and encrypted backups.

Workflow

• Install AuthGeek from the official site or GitHub release
• Launch the application
• Create a vault password (Argon2id derived key)
• Add accounts by scanning QR codes or pasting secrets
• Generate TOTP/HOTP codes directly on the desktop
• Backup the encrypted vault if needed
• Restore the vault on another machine using the backup

Evidence

AuthGeek is a TOTP and HOTP authenticator that keeps everything local: Secrets in a local vault, encrypted with Argon2id; No account, no sync, no telemetry
