Return Value

Type: Boolean
Must return false in case if this authentication method requires login and password, or true is the account name is included in the password (for instance, in case of OAuth method). If RequiresCredentials is false, this method has no effect.

In most cases, this method should return false. In OAuth case, the account name is not defined, you only need to supply the account signature which includes multiple parameters (some of which may be treated as the password).
