Once you’ve registered a WordPress account, your password account will remain the same, unless you change it manually.
If you want to modify your WordPress password using a desktop computer, follow along below.
1 Log in
by going to www.[yourwordpresssitename].com/wp-login.php? and entering your username and password.
2 Users > Your profile
is what you need to select in the menu once you arrive in the WP dashboard.
3 Scroll down
till you find under biographical info the field New password and Repeat new password.
Type the new one you want twice.
4 Update profile
is the button you need to click on on the bottom of the page.
Once you click now, you will notice a message that your profile is updated (and so is your password).
