What GAuth is

GAuth is a free, open-source application for multi-factor authentication using the TOTP time-based one-time-password algorithm specified by RFC 6238. It is available as a hosted web application at gauth.apps.gbraad.nl, or as static files that can be served from Apache, nginx or another web host for self-hosting. Adding an account requires an account name and secret key, and settings provide an option to export keys. The project uses HTML, jQuery Mobile, jsSHA, LocalStorage and Application Cache. Its compatibility information names Google Authenticator, Dropbox, Dreamhost, Amazon, Linode and Okta among supported services. Source code is linked in the About section and available in a public GitHub repository. GAuth is licensed under the GPL, identifies Gerard Braad as its author and directs problem reports to the GitHub issue tracker. The listed platforms are web and self-hosted. No push approvals, encrypted backup, multi-device synchronization or team administration are listed.
