Add Support for Passwordless Authentication with OTP

[marcusdacoregio]

We should add support for one time token authentication, one common example is magic links sent in email or a text code to log a user in.

Note that this is not the same as https://github.com/spring-projects/spring-security/issues/3046 since it is not in the scope of this ticket to support MFA.

Hi, @marcusdacoregio can I work on it?

Hi @evgeniycheban, this feature will require several design interactions with the team members since we have other features in the horizon that might be affected by it (MFA for example). Because of that I think it will be better if one of the maintainers work on it.

However, since you have an extensive knowledge of the code base and have contributed to a few core features, I'd love to hear how you see this feature implemented, either a high level idea or some code.
