I'm designing a forms authentication site (all in ASP.NET with VB.NET) at
the moment with the intention of going to passport some time in the future,
what is the best way to go about this - should I have the usernames as
e-mail address's, is there anything else that I need to take in to
consideration - what will make the transition easier?

Thanks,

Phil

that sounds like an interesting challenge you have there. the part that i feel pulled to is the transition process from the user's perspective. it seems that when you move to passport you will require each user to:

- ensure they have a Passport, and create one if not.
- log into their passport account
- match their newly created Passport to their account on the web site

I think I'm right in saying that Passport guarantees to provide nothing more than the person's unique user ID which means matching up Passport accounts with web site accounts will need to be done manually. I suppose the scale of the problem really depends on what percentage of Passport accounts will provide an email address that you can use to match up Passport accounts with your existing member accounts.

Email addresses seems a fair way to go, although if you know you're going to move to Passport, maybe there are strong enough reasons to do it now? I'd suggest you do not key users around email addresses, but give them all a unique ID that you can 1-1 map to Passport user IDs. I believe that a Passport user can change their email address. From a usability perspective there appear to be some benefits in using email addresses as logins, but technically I can't see it makes much differences.

There's a Passport piece on ASPToday at the following address (subscription only), although the code relates to .NET beta 1.

any help?
