Trazzler does a pretty good job with this -- using Facebook Connect. I've documented the steps here:<div><br></div><div><a href="https://wiki.openid.net/Trazzler-profile-linking">https://wiki.openid.net/Trazzler-profile-linking</a><br>

I agree that when supporting multiple login mechanisms, it's important for the site to let you easily merge accounts. One way to do this is to request your email via SREG or AX and proactively look out for you. Another approach is when you login with a new identifier, to ask if you already have an account and let you merge then.<br>

I have a friendfeed account with my gmail address. Friendfeed now supports<br>
Google and facebook login.<br>
So I log in with my google account. No problem. I also have a facebook<br>
account with the same email address.<br>
<br>
When I log in with my Facebook account it see's me as a new user obviously.<br>
They cant get your email address from facebook. So I add the same email<br>
address to this account. I logout and login with google again and it takes<br>
me to this new account!<br>
<br>
Then I close my browser and login again with my facebook and it recognizes<br>
my old account! No problem.<br>
<br>
Now this is the problem. Most sites maintain accounts based on email<br>
addresses. It is is very difficult to integrate third party signin's<br>
whithout email addresses. Friendfeed seems to have pulled it off with some<br>
glitches though.<br>
<br>
If OpenId needs to seemlessly integrate with RP's email based authentication<br>
SREG email is an absolute necessity.<br>
<br>
