If you’re someone who manages a lot of Basecamp accounts and has a hard time remembering passwords, this post is for you.

There are a lot of authentication systems emerging, Facebook, Twitter, and Google all allow apps to let users login using their credentials.  Open ID is an open authentication system that a variety of providers operate.  It’s a godsend if you “can’t remember your passwords? tired of filling out registration forms?”

I have a lot (12, precisely) of Basecamp accounts.  We run it for Flatsourcing, and I’m pulled into a lot of client’s accounts.  I used to have to remember the URL, username, & password for each one.  That’s 36 things to remember, and countless combination of things.

Now I just remember a single URL and password with OpenID.  It’s awesome.

Here’s what you need to do:

• Create an Open ID.  I use myOpenID.  There are a lot of providers.
• Log into Basecamp and click “my info” in the upper right.
• In the area for your username & password, click “Use OpenID” and enter yours
• When you land on the login screen, click “Login using an OpenID instead” and enter yours
• You’ll be taken to your Open ID provider to enter your password and then voilà, you’re in
• HUGE BONUS - Basecamp has an “Open Bar” that is a drop down of all your Basecamp accounts (actually all your 37 Signal product accounts).  These are all now connected and easy to switch back and forth between.  This feature alone makes switching to OpenID for authentication well worth it.  That and you have 36 memory slots freed up.

Enjoy!
