To log in to your site, click on the Log in link in the footer of your site. You can also add “/wp-admin” to your homepage URL, and you will be taken to the login screen. On the login screen that appears, use the username and password provided you received via email.
Before logging in for the first time, you'll be prompted to change your password. Be sure to use a secure password and be sure to log out of your site after you are finished working on it. To change your password any time after that, find the user account and click edit. Scroll down to the bottom of the account and click Set New Password. Either keep the generated password provided or type in a new one. Click Update User to save.
*You'll know the password was accepted if it says "User Updated" at the top of the page. If not, you'll need to try a more secure password.
