https://discussions.apple.com/thread/253554667?answerId=256821907022#256821907022SOLVED for me!
I had the same problem. Just figure out that I needed to change keyboard language (ABC is default, bud I use Czech QUERTY)!
Great that it worked for you @aneta2244! I did try that on mine (setting to American, and then to the possible QWERTY variants) and it did not work for me. Definitely worth trying in case it does!
Had exactly same issue. I was able to fix it by reset NVRAM/PRAM. Restart your computer and press Command + Option + P + R keys at the same time for about 20 seconds. Then release the key it will boot into login page. Enter you password again see if it works
还有一个地方:就是把输入的登陆密码清空,那里有一个问号,然后重设密码试试。我三个方法都试了,最后重设成功了。
