Works online and offline • Generate codes locally without any server connection • Optionally sync with your 2FAuth server for multi-device access • Continue accessing codes even when your server is unavailable

Multi-server support • Connect and manage multiple 2FAuth servers • View and organize codes from different servers in one place

Organize your accounts • Group accounts for easier navigation • View both current and upcoming codes at a glance

Account and server management • Add and edit accounts when connected to your server • Manage users and perform administrative actions (server-dependent)
