Bulk migration options do not support migration of passwords. Auth0 uses bcrypt for storing passwords and of course there is no way to convert passwords hashed with one method into another method. In this scenario your users would have to reset their passwords. At this time there is no way around this as far as I know.
Automatic migration will migrate your passwords as Auth0 has the opportunity to capture the password during login and hash it with bcrypt. This is the method I am using where I work. It is very important to get the login and get user scripts right, but once they are in place this method works quite well.
we basically relied on username password authentication, we don’t have username and his associated email address in my system.
Automatic Migration option wont be usable in my case. Even for Automatic migration email address is not there only username will be there, Not sure Automatic migration will work without email.
For Bulk migration my system relies on Username only ,
so no way to reset password in Auth0, since reset password is based on email verification.
Is there way to set security question verification and password reset ?
I did some research and it seems like we do not offer any kind of security question verification. The only blog post in general we have about it is here:
