Inconvenience != Security

Many people have suggested idea for how they can better secure their users from doing stupid mistakes and ask for my opinion.  Most of these ideas (IMO) seems to add just inconvenience to the user without improving security.  So, my quote for this has been

"While security is not convenient, just inconvenience is not security either!"

Consider this captcha below which illustrates this point ( credit - http://random.irb.hr/signup.php ) 

I would always tell my customers consider their users/clients and think ....

• Just inconvenience to your customers does not provide security
• Sometime simplicity is the answer to complex questions
• Understand your customer's context 
• Think security !
