Adding a dynamic link to member area (for Single Sign On purposes)

To make Single Sign On strategy easy, I would like to simply programmatically add a dynamic link to the user's member page.

It should be something like: www.mysite.com/autologin/secret-long-autologin-key-here

It needs to be dynamic so I can generate a random hash for it.

Or if there is another simpler way to do Single Sign On I would love it.

Exactly what I needed.

These things should be easier to find in the documentation, thank you

I did it and it works beautifully, I have a secret formula to generate a hash from the user information and I use that same one on the other side to check it, works beautifully, and expires in one minute.
