When you try to login to your Magento 2 admin, you got this message You did not sign in correctly or your account is temporarily disabled . You don’t know that you are not using username or password. In this guide, I will show to how to resolve this sign in problem “You did not sign in correctly or your account is temporarily disabled”.

The fix was to make sure there is 1 alpha character and 1 numeric character in the admin password. This should be labelled a bug if the password is not validated during install with magento setup:install

Solution: Unlock admin account

try command in case the account is locked

php bin/magento admin:user:unlock 

Or go to Magento 2 root folder and type

php bin/magento admin:user:unlock
