How to reset your Microsoft account password
Go to the Reset your password page.

The account recovery form is meant to be the last option to get you back into your account. If you haven’t tried resetting your password yet, first go to When you can't sign in to your Microsoft account for troubleshooting suggestions. If, however, you can’t reset your password or an attacker changed your account settings, the recovery form gives you a chance to prove that you own your account.

Security info & security codes
Security info is an alternate email address or phone number that you add to your account. If you forget your password, or if someone else is trying to take over your account, we send a security code to that alternate email or phone number. When you give the code back to us, we know that you’re really you and we can get you back into your Microsoft account.
