About OTPClient

OTPClient is a two-factor authentication client for the Linux desktop, written in C with a GTK4 and libadwaita interface. It supports TOTP and HOTP with SHA1, SHA256 and SHA512, otpauth:// URIs and QR codes, and Steam Guard codes.

Codes are hidden by default and copied on demand. Tokens live in encrypted databases, several of which can be listed in a sidebar, with grouping, drag-and-drop ordering and cross-database search. A command-line interface and desktop search integration are included.

Strengths

  • Multiple encrypted token databases
  • Supports TOTP, HOTP and Steam Guard codes
  • Codes hidden until needed
  • Includes a CLI and desktop search integration

Limitations

  • Desktop Linux only, no mobile app
  • Handles one-time codes only, not passwords
