Since I didn't receive a reply from you in the chat, I've moved the conversation to this support ticket.
When I tried to log in to the admin area, it redirects to a different sub-domain "account.{yourwebsite.com}/wp-login.php". When I used the username and the password that you've shared, it shows the incorrect password message.
Can you please check the username and the password again and also share the exact link to the login page?
