If you need mostly B2C features I would have a look at Clerk [0] and Supertokens [1]
If you are more interested in B2B features we found Ory [2], FusionAuth [3], and good old Keycloak [4].
None of them are fully comparable yet however, which might be the reason why they might get away with their current behaviour.
