hello koders, i hope your doing fine . i want to create a login page only no need for signup
let me give you an example
‘‘i created an educative app , person A sent me the subscription money for a month + his email, and i gave him his password and usename so he can login to the app .Now, A’s subscription has ended and i need to delete his username and password so he can not login again to the app’’
how can i make a login page like that with blocks and connect it to firebase
