Password (account) not working after migration on new mac
I had opened my new mac computer with no problem entering the new mac computer initially. Then after updating the software identical to my mac book air, I started the migration process from my mac book air to my new mac computer, starting by migrating my account. After that process I was asked to put in my password on the new mac computer. Unfortunately I can't enter the mac computer any more because the password (the same for both my mac book air and my new Mac computer ) is not working . I have tried to write in qwerty and azerty keyboard style but nothing seems to solve the issue , as if the password is incorrect, which seems very unlikely. How can I solve this issue; I am completely stuck and don't know how solve this strange issue.
