Managing multiple WordPress sites can take time and present challenges for most WordPress users. For this reason, Bluehost has built an exclusive section of the Bluehost WordPress hosting experience dedicated to easily managing all of your WordPress sites.
Now you can easily install WordPress and manage WordPress sites in the new Bluehost interface.
You can log into a WordPress site without entering username and password.
However, sometimes you have problem log into a WordPress site within the Bluehost interface. For example, if you have migrated a WordPress site from other webhosting comapany to Bluehost, this problem may occur.
In this case, you can log into the WordPress by accessing the admin login page such as www.example.com/wp-admin.
If you forgot admin login credentials, you can reset the password via the DB. (You can access the DB using phpMyAdmin.)
I think Bluehost offers a cost-effective webhosting service. If you want cheap but relatively good resources, you might want to consider Bluehost. Bluehost now support up to PHP 7.2 which improves the site performance.
Just for your reference, if you sign up for a web hosting service by clicking on a referral link contained in this post, I will get some commission. However, I do not recommend a specific service just for commission. I've been using several webhosting services for years including SiteGround and Bluehost.
Most especially, if you sign up for Bluehost's Shared Hosting by clicking this link, you can use a Bluehost webhosting service with US$1/mo off starting from US$2.95.
