I just downloaded the Photosynth iPhone app and when I try to log into Windows Live with my Hotmail address it says "Invalid Username or Password". I tried time and time again and it won't let me in. I'm definitely typing in the correct username and password - I can log into or hotmail etc from my phone with the same user/pass. 

The same user pass also works fine to log into on my computer.

I tried to log in with a friends hotmail address and that worked fine so it seems like their might be something wrong with my live account.

Can't log in. Created an account on Photosynth using my address that I have had for about 10 years and I can log in fine to the website, just not on my iPhone. Restarted iPhone just in case. Still not working, constantly reports invalid username and password, and if you do it too many times locks you out of your Hotmail account due to too many incorrect password attempts - nice!

I believe that your old password is probably too long. If you go to and change your password, you'll find that you can't enter more than 16 characters. This has been true for the past half a decade.

I have the same issue. The hotmail account and password do not work to login and show the invalid username/password message. Again, like the above, I'm able to login to email or the photosynth site with issue

@blitz99, if I'm right, older passwords that have more than 16 characters continue to work on most Live ID forms, however the newer web forms which Photosynth uses only send the first 16 characters typed, since that is all that has been allowed to be registered in recent history.

If an older password is longer than that, then it will not match what you originally entered and the login will fail. 

I know that it is inconvenient to have to change your password, but please just try it and I don't believe you'll ever see this error again. Chances are that more of Microsoft's services will use this modern 16 character login limit in the future, so you'll be doing yourself a favor to just update your password to fit within their modern limits.

If you do try this and it does not resolve the error, please write back and let me know, but so far everyone who has tried it has reported success to me.

Hi there,

Sorry I didn't get back sooner, there is no way to get notification that someone has replied to a post here.

I did reset the password prior to posting, this does not work. I'm pretty sure I didn't have a password longer than 16 characters anyway.

I still get invalid username or password - despite being able to log in from my computer - just iPhone having this issue.

Unable to share any images here!

MS, can I just say that you'd benefit from some kind of follow up notification system on this forum!
