Warning: I wrote this blog in 2008. That is a long time ago, especially on the internet. My opinions may have changed since then. Technological progress may have made this information completely obsolete. Proceed with caution.

Here is a message I got after logging into a website recently:

**** NOTE **** Using a colon (“:”) in your password can create problems when logging in to Banner Self Service. If your password includes a colon, please change it using the PWManager link below.

Protip: If you are designing any kind of login/authentication system and you find that you need to give users a warning similar to this, you are doing something wrong.

On a much more nitpicky side note, why not just make “PWManager” or “using the PWManager” link to PWManager? To their credit, at least they didn’t say “by clicking the PWManager link below.”
