Once you are logged in, go to Users » Your Profile from your WordPress menu.
You must scroll down to the Account Management section of your WordPress profile to find the New Password option. To create a new password, click the ‘Generate Password’ button.
WordPress will generate a strong password for you automatically.
You have the option of keeping this strong password or changing it to a new one. Then, to save your new password, click the ‘Update Profile’ button.
When you’re finished, you’ll see a Profile Updated notification at the top of the page. WordPress will also send you an email with a password change notification.
