I have not been able to log into minecraft since noon today. There's a permanent message that either the email or the password is incorrect. I changed the password several times and I'm 100% sure that the data was entered correctly. Maybe one of you can help me
If you have entered incorrect data too often, you will be blocked for a few hours and can't log in with the correct data.
It's best to change the IP and try again. Then it should work.
Take a look at the passwords so that you disclose them and check for errors. And go through all your passwords
