Windows 10 allows for an unlimited number of login attempts. There is no specific limit set for the number of login attempts, but if the user enters the wrong password for multiple times, Windows 10 can lock their account for a specified amount of time. This is a security measure to protect the user's account from unauthorized access. In case the user forgets their password, there are a few steps they can take.
1. They can use the password hint feature to help them remember their password.
2. They can use a secondary email or phone number associated with their Microsoft account to reset their password.
3. They can use a recovery disk or USB drive created beforehand to reset their password.
4. They can access their Windows 10 device from another administrator account and reset their password.
It's important to note that the number of login attempts may vary depending on the settings, such as account lockout policies set by the network administrator or IT department. It's also recommended to create a strong password and enable two-factor authentication to enhance the security of the user's account.
