i think these days the best practice for mobile apps re retention (other than sso or passkey) is to just ask for an email, then from the validate link continue with register

reason being that more steps to register means more ways people are likely to drop out of the flow, and this is basically about as short as it can be

when the user has validated their email, then they’re more invested so they are more likely to complete

that also fits nicely with what we’re talking about with good security

Just to clarify, would you mean to have the email/validate stage as part of the flow to access the app, or let them continue with just the email with a limited functionality?

either… some apps have just started to do single factor login with just email, profile options can be optional, if there are required fields or terms of service to agree to then that can come after email validation
