Disable Password Saving in Web Browsers

On this page:

Overview

Most recent versions of web browsers prompt you to save usernames and passwords for various sites on the Internet. This feature can be useful, but can also put your money and personal information at risk if you are not careful.
Information Services and Technology recommends that you do not save passwords with your browser for sites which have:

  • Private information about you or someone else (e.g., medical records);
  • Private financial information (e.g., credit card numbers);
  • Private correspondence (e.g., email).

For example, you should never save the passwords for your accounts with:

  • Fidelity NetBenefits;
  • MIT Federal Credit Union, or your bank;
  • MIT WebMail.

You put yourself at risk when you save passwords for these types of sites.
Below are instructions to disable the password saving feature, or to force the browser to clear all currently saved passwords, on commonly used browsers.

Note: Passwords for individual websites are not the same as the certificate, or master browser password which should be in place to protect your MIT Personal Certificate, and which will not be affected by these instructions.
