Authenticator

Two-factor authentication app for securing online accounts.

Description

Microsoft Authenticator — generates time-based one-time passwords (TOTP) and supports push notifications for Microsoft accounts.

Download or use

Available on iOS and Android app stores.

Reasoning for

Essential security layer for all important accounts. I use it alongside 1Password — 1Password for passwords, Authenticator for 2FA codes.

Alternatives considered

  • Google Authenticator — simpler but less features
  • Authy — multi-device sync but more complex
