Accounts and authentication secrets

Accounts are the services that require an authentication code as a second factor to sign in. e.g. AWS, GitHub, AWS

When you enable multi-factor authentication on those services and add an device, you will usually be presented with a QR code to scan. There should also be an option to display the secret encoded in the QR code. This secret should be a Base32 encoded string and is the secret you enter when prompted by the add command.

mfacode stores the secret in whatever secret store is provided by the operating system (DPAPI for windows, Keychain for OSX)
