USB-Dongle Authentication is a community-maintained directory that helps people compare the account security options offered by online services. Its listings cover websites across categories such as cloud storage and backup, banking, and financial services, with each entry indicating whether the service supports one-time passwords (OTP) or security keys using WebAuthn, FIDO2, or U2F. Some listings also identify support for using more than one security dongle and link to documentation for setup or further details.

The directory includes a broad range of providers, from Apple iCloud, Dropbox, and Google Drive to banks and credit unions in different countries. It also records when dongles are not supported, giving visitors a useful overview of the authentication methods reported for each service. Users can consult related information about security dongles and their supported protocols, and contribute additions or corrections by submitting a pull request to the project’s GitHub repository.

This resource is designed to make it easier to assess and compare two-factor authentication support across commonly used websites
