The 2FA directory contains an organized overview of which websites and services offer 2FA support. The websites are grouped by category. Each website has a link to the documentation. The 2FA support is subdivided by the kind of support, e.g., SMS, hardware-, or software tokens.

The repository hosts an Aegis compatible icon set based on the Simple Icons collection of popular brands. The icon set can be loaded into compatible apps, like the Yubico Authenticator, and will show nice icons next to the different tokens.
