There are so many product design options for user registration and signin these days: email/password, Facebook login, Google auth, SMS PIN numbers... so what are the current best practices, and where's the data to support them? [more inside]
Tumblr and Google are now using two page login processes where you first enter your username or email and then are sent to a second page to enter your password. What's the reason/logic behind this switch from the standard two item form?
The situation is that I manage a bunch of websites & web services, all with their own separate user accounts. It would be useful to unify all these logins. The problem is that the software infrastructure necessary to support unified logins is way beyond my capabilities. Is there a suitable technology shortcut or a way I can cheaply buy such a service?

I have moved from Argentina back to the UK. Whilst there I set up my Google account with 2-Step Verification using my Argentinian phone number. Now back in the UK I no longer have access to that phone and as I unpacked I realised I threw away the notebook in which I jotted down the emergency codes in the move. Am I screwed? [more inside]
A couple of years ago I met Joe Torre, totally outside of a baseball context. He graciously gave me two signed baseballs, with no fanfare, just reached into his pockets and came out with two balls wrapped in tissue paper saying, "Want some balls?" Well, yes, of course I wanted them, and I took them home and socked them away thinking that someday—maybe when he was inducted to the baseball hall of fame—I would sell them. Well, Joe's been voted in, and I'd like to explore the best way to put my memorabilia on the market. I'm curious how to go about that. [more inside]
Does third-party use of Google Authenticator go through the Google panopticon? If I use Google Authenticator on a third-party site, will that interaction send information back to Google, thereby informing Google of what I'm doing? [more inside]

I bought a Thinkpad through Gumtree (UK) last year and now Microsoft Office Professional Plus 10 is asking me for an authentication code. When I got the computer, windows had just been installed but I don't know if I got a trial version or a corporate version that was imaged onto the machine. Do I need to pay for an authentication code or is there a way to otherwise disable the authentication request message?

On one of my WordPress hosted blogs, I previously used Angsuman’s Authenticated WordPress Plugin to restrict access to registered users. After upgrading to WordPress 2.7, the plugin doesn't work anymore. It won't let anybody log in, trapping people in a constant loop of entering (correct) passwords and being returned to the login screen. [more inside]

I manage a website. Some content requires authentication by password or IP. I want Google to crawl that content but not cache it, so that Google users can find it in searches but can't access it without authentication. What's the best way to do this? In 2006 Matt Cutts recommended doing a reverse DNS lookup to verify that a bot's name is in the googlebot.com domain, and then a forward DNS->IP lookup using that googlebot.com name (to thwart spoofers). Is that still the best solution? How do other people manage this?

I have an application installed on my PC at work that needs to connect to the internet through our ISA Server. The problem it has is that it can't connect directly unless I put in proxy settings. The problem that I have is that the proxy setting is just one long URL with no username or password. How can I get this application to connect? [more inside]
I have noticed that there seems to be a split between some banks/financial institutions who maintain complex security around their on-line account access and others who seem to have actively migrated towards a much simpler approach. Is there any evidence that the "simple" approach is either more or less secure than the "complex" one? [more inside]

How exactly does authentication work in a website like Basecamp, or more generally, a site built on Rails or LAMP. When I sign-up, I enter a username and password. I presume this is stored in a database table. But after that, how does the server know who I am during the course of my 'visits' and how does the SQL database know what I have access to ( only my projects ) and what I don't have access to ( Other peoples projects)? Where do cookies, if at all, come into play. If cookies do come into play, can they not simply be forged? I am completely clueless regarding the subtleties of authentication, user sessions, and security. Please enlighten me.

Why are many financial institutions moving to a two-step login process, where you enter your username on one page and then your password on the next? For instance, Vanguard and ING. Their rationale is just that it's "more secure", but that's not much of a reason.

I'm trying to get my application (VB, but that doesn't matter) to connect to the internet and support proxy servers that require a username and password. The former is easy, the latter not. What I'm doing is sending Proxy-Authorization: Basic [authentication] in the header (where [authentication] is "username:password" base64 encoded) with each request. However the proxy server keeps reporting error 407 (authentication required). I've read the RFC's, I've read google groups but I have no idea what I'm doing wrong. Any ideas?
I'm behind a university proxy firewall and wanting to access ports that are blocked from direct access through the firewall. I was wondering if there are any telnet clients out there that have HTTP-proxy capabilities with authication (user/password) as well.
