Good evening Jessica and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
I would love to help you with this topic.
The simplest solution would be to use the fields found in Events -> Settings -> Display (Scroll all the way down to Advanced Template Settings)
Another solution would be to use a third-party plugin such as: https://wordpress.org/plugins/theme-my-login/ which gives you greater control over login look and feature.
Let me know if that helps.
Have a great day!
Geoff B.
