You can use our email password feature to store abs verify the password hashes. And you can use argon2 hashing as well

You can even hack your way around having this hashing algorithm using our overrides feature on the backend SDK.

By overriding the email password recipe functions

Such that in your override, before calling the original implementation, you do this hashing yourself. This way, the password are first hashes using PBKDF2 and then hashes using argon2 in the core. Doing this double hashing shouldn’t really cause any issues from a security point of view anyway, and give you what you are looking for
