Blazor Web App - User Authentication

I'm looking for a Blazor developer to implement an authentication system in my web app. The system should:

- Utilize individual user accounts
- Mandate email verification for new users
- Ensure that all users have the same access level

there are two authentication paths

1) in root site (create authentication with sql server)
http://www.mywebsite.com :

user :
password :
identification or licence

in this path I will show data specific to licence (like billing, expiration of licence ... out of scope of this project)

2) in root/licence/*
http://www.mywebsite.com/{licence} : query if licence exists
http://www.mywebsite.com/{identification} : query if identification exists and returns licence
http://www.mywebsite.com/{licence}/basedatos_01 : in list of enterprises select by default this db

token must be saved in session or locally , it must used in next calls to api

in login interface there are several fields like dll version , db version , licence expiration ...that is return with a call to an api
