Log in a user using magiclink or a one-time password (OTP).

If the {{ .ConfirmationURL }} variable is specified in the email template, a magiclink will be sent. If the {{ .Token }} variable is specified in the email template, an OTP will be sent. If you're using phone sign-ins, only an OTP will be sent. You won't be able to send a magiclink for phone sign-ins.

Be aware that you may get back an error message that will not distinguish between the cases where the account does not exist or, that the account can only be accessed via social login.

Do note that you will need to configure a Whatsapp sender on Twilio if you are using phone sign in with the 'whatsapp' channel. The whatsapp channel is not supported on other providers at this time. This method supports PKCE when an email is passed.
