Do I have to register for your site to buy something, etc? Then don’t make me freaking GUESS at what your password requirements are. If you have some, then show me what you need before I put in one that I know is strong and hit the Register button…
…only to have it come back and tell me I need a numeral. Or a capital letter. Or some other made up requirement that you NOW tell me about.
The user experience for your product or service starts before your potential customer ever gets it. Don’t make me think you suck before I even pay you.
