2FAS is an authenticator and password manager for iOS, Android and browsers. The 2FAS Auth app generates two-factor codes for online accounts and supports backups, token groups and icons, while 2FAS Pass stores passwords with browser autofill and sharing. According to the vendor, tokens and passwords are stored locally on the device, the company does not see user data, no account is required, and cloud or manual backups are optional.
2FAS is operated by Two Factor Authentication Service, Inc., a Delaware corporation whose mailing address is in Henderson, Nevada. The company is therefore seated in the United States and subject to US jurisdiction. The source code of the 2FAS Auth apps is published on GitHub under the GPL-3.0 licence, with graphics excluded and covered by separate terms. The privacy policy includes GDPR provisions for EEA residents. For a European user, local storage and the location of any optional cloud backup are the main factors; the vendor does not state where optional backups are stored.
