About 2FAS Auth

2FAS Auth stores tokens on your device and does not require an account. It offers cloud or manual backup, and you control how tokens are stored. Groups, badges, icons and labels help organize codes, and an Apple Watch app is available alongside the iOS and Android apps and the browser extension.

The company describes the project as open source and source-available. Its public repositories for the iOS and Android Auth apps are under GPL-3.0, and a Cryptography White Paper documents the algorithms and design choices. Because the site uses both terms, check the license of each repository before you rely on the claim.
