If you can't remember your password, your password isn't
working (and you've made sure Caps Lock is off), or if you think
someone has stolen or hacked your Microsoft account, go here to reset your password.
There are two ways forward, depending on how you’ve set up or used your account:
If you've added security info to your account,
we'll send a one-time code to the alternate phone number or email
address you gave us. When you enter that code on the next screen, you'll
be able to make a new password.
If you don't have or can't get to your alternate phone number or email address, tap I don't have access to these.
You'll go to a security questionnaire, where you’ll be asked for info
like the subject lines of email you recently sent from your account,
your birthdate, credit card info, and other details only you would know.
To recover a hacked account
Try to sign in to your Microsoft account
Do one of the following:
If you can still sign in to your
Microsoft account, you should change your password immediately, so
whoever stole your old password can no longer use it. Tap or click the
Security & password page, tap or click Change your password, and then follow the instructions.
If you can't sign in to your account, a hacker might have changed your password and taken over your account. Tap or click Can't access your account?, select I think someone else is using my Microsoft account, tap or click Next, and follow the instructions.
