Your Cal U Email authentication for your phone is changing.
There are 2 types of Authentication that can be used for checking email on a phone – Modern and Legacy Auth. Due to security reasons, Modern is what you want to use and Legacy Auth will soon be disabled.
If your phone stops checking email, you likely will need to switch it to use Modern Authentication using the guides below.
iPhone: There are 2 ways to set up the native iPhone email app: Manually and Automatically by clicking Sign In. Choosing Manually gets you Auth.
