Comparison of OAuth providers
Are the accounts unique? (Are multiple accounts discouraged?)
The reason I made this page is to try to find ID providers that supply more or less unique accounts.
Note that no one can really guarantee unique accounts unless they can use data from the authorities (and even the authorities' data may contain false entries).
