A community-maintained dataset and API listing websites and services that support two-factor authentication, covering SMS, email, hardware, and software methods. It powers the 2fa.directory website and helps users compare services based on their 2FA support.
Use cases
- find out which websites support two-factor authentication
- check if a service offers 2FA before signing up
- get a list of sites supporting hardware token authentication
- query an API for 2FA support data for my app
- compare security features of alternative services
- research which sites support SMS vs app-based 2FA
When to choose
- you need comprehensive, community-verified data on 2FA support across websites
- you want a free API for 2FA support information with attribution
- you're building a tool that helps users choose more secure services
When to avoid
- you need to implement 2FA in your own application rather than look up which sites support it
- you need real-time or guaranteed-accurate security data without manual verification
- you want to scrape the repository directly instead of using the provided API
