Security Best Practices for Comerica Web Banking

To help avoid an online security breach, you should periodically update your Comerica Web Banking profile. Changing your User ID, password and security questions every 90 days will help prevent unauthorized people from accessing your account. It’s also important to update your personal contact information (email address and phone number), so we can easily contact you regarding security concerns related to your Comerica account(s).

Make sure your User IDs and passwords contain a mix of numbers and letters, so they can’t be easily guessed. Do not use names, like your mother’s maiden name; familiar dates, like your birthday or anniversary; or your Social Security number. Avoid using any information in your User ID and password that someone could find elsewhere on the Internet. Comerica Web Banking recommends alphanumeric passwords for your security.

User ID Guidelines

Your User ID must be 8 to 15 characters in length and consist of letters (a-z or A-Z) and numbers (0-9). Spaces and special characters (!, #, $, &, @) are not permitted.
Do not select a User ID that is similar to your password.
We recommend changing your User ID every 90 days.

Password Guidelines

Passwords must be 8 to 32 characters in length with no spaces and must consist of letters (a-z or A-Z) and numbers (0-9) and at least one special character (- . , @ : ! $ /).
Passwords are case sensitive. When creating your password, if you choose to capitalize a letter (such as "A" versus "a"), you will need to enter it exactly the same way at every login. Example: 24karatgold versus 24KaratGold.
Do not select a password that is similar to your User ID.
We recommend changing your password every 90 days.
