Hotmail and Outlook Single Use Code to sign in with

Whenever possible I prefer not to enter login information on third party computer systems and networks.
Why? Because I do not have full control over the software running in the background or in the same network.
Other means of logging in are preferred, especially passwords that are only valid once and expire afterwards.
That's what Hotmail has added to their website recently.
Update: The very same feature is also available on Outlook.com, Microsoft's new email service.
When you open the Windows Live Hotmail website you see the standard Hotmail sign in screen for the most part. If you look below the Sign In button you see this:
Not your computer? Get a single use code to sign in with
The sign in form changes when you click on the link. You are now asked to enter your Windows Live ID and the single use code instead of your regular password to log in to the service.
This is also indicated at the top where it states:
sign in with single use code. If you're signing in from a public computer, you can use a single use code instead of your password for added security.
If you do not have a code yet you can request one with a click on Get one here on the same page. You are then asked to enter your Windows Live ID and a mobile phone number that is linked to the account.
Microsoft will send a text message to the phone number that includes the single use code that you can use to sign in to Hotmail.
If you have not linked a mobile phone number to your Windows Live account yet you can do so in the account settings. Open the link and enter your login information. Click on Security & privacy once you are signed in and there on the "add a new phone number" link on the page.
The mobile phone number needs to be confirmed before it can be used for single use codes. Hotmail sends an email to the linked account email address.
This email contains a confirmation link that you need to load to confirm the addition of the mobile phone number to the account. This obviously only adds to security if you do not use Hotmail as your email provider for that account email address.
Once the number has been verified you can start requesting single use codes for your Hotmail sign ins.
Single use codes are actually available on all Windows Live sign in forms.
The addition of single use codes adds to Hotmail's and Windows Live's security big time. What's your take on this? (via)

You said that Outlook isn’t your main email client, so which is your main one?
I think its thunderbird
It is Mozilla Thunderbird.
Awesome! This actually solved my problem… what a stupid bug.
If this is the same bug that I’ve encountered, there may be another fix: (1) hover over open Outlook item in Taskbar, cursor up to hover over Outlook window item, and right-click; (2) this should give you Restore / Move / Size / Minimize / Maximize — choose Move or Size; (3) use your cursor keys, going arbitrarily N/S/E/W, to try to move or size the Outlook window back into view. Basically, the app behaves as though it were open in a 0x0 window, or at a location that’s offscreen, and this will frequently work to resize and/or move the window. Don’t forget to close while resized/moved, so that Outlook remembers the size/position for next time.
THANK YOU Claude!!! I could get the main window to launch but could not get any other message window to show on the desktop. You are my hero!!!!
Solved my issue! 6 years later and this is still problem…
Fantastic. Thank you. Size did the trick.
This solved my Outlook problem, too. Thank you. :)
Thank you so much, this started happening to me today and was causing big problems. You are a life saver, I hope I can help you in some way some day.
You are a god – thank you!

Yah…thanks Claude. I’ve been having the same problem and tried all the suggestions…your solution was the answer. It had resized itself to a 0/0 box. Cheers

Thanks a lot for the article. Don’t know why it happenend, don’t know how it got fixed, but it was really annoying and now it works :-)
Thanks a lot. I was facing this issue from past 3 week. I tried everything but no resolution. The issue was happening intermittently and mainly when I was changing the display of screen ( as i use 2 monitors). The only option i had was to do system restore. But thanks to you.
I’ve been tried to sole this problem for 12hours. Your comment about changing the display of screen helped me a lot!! Thanks!!
Thank you…don’t know why this happened but your instructions helped me fix it. Running Windows 10 and office pro 2007

Thank you again. M
This problem was faced by only one user logging to TS 2008 r2 using outlook 2010.The issue was resolved.
Thanks.
Great tip. Thank you!!!! If it helps, I had to use the Control Key and the arrow keys at the same time to bring my window back into view. Worked like a charm.
Thank you, this worked !!!!
