I’ve tried resetting it a few times with suggestions and instructions I found here and elsewhere on the web. I keep getting stuck because I don’t know his username. From what I can tell, what I thought was the username isn’t working in my attempt to reset the password.

I'm working on a Ubuntu system, and my client has completely forgotten his administrative password. He doesn't even remember entering one; however it is there.  I've tried the suggestions on the website, and I have been unsuccessful in deleting the password so that I can download applets required for running some files. Is there a solution?

If I change the password for the root user is that going to automatically change the password for the user account?   I found this link for root:    How do I change the user account password?

It shows no question owner, not even a simple name (without link).   What happened?

So I paid for a minecraft account and everything but when I try to log in it says that I don't have a username. Is it an email or an email that you've made just for this account?

My Minecraft password will not work. I've reset it about 5 times and no matter what I choose as my password, it will not take it. I just made my Minecraft account today   I am entering my username correctly, and I am typing everything in the correct boxes, but it always says "Unknown username or password...". I know I am putting my username in correctly because if I try to re-register, it will not let me use my email because it's currently in use.  Could somebody explain to my why no matter what my Minecraft password is, it won't work?

I do not have Google+, I do not have 2 step verification, and I have no data to show in my data tools tab online.  So, why do I keep getting an error message that my password is incorrect or my account has changed?  I didn't change anything, in fact, I never use it.  Have I been hacked?  If so, how can I resolve this so it doesn't keep happening?

This question has probably been asked before, but I just can't find my name. , but the reason that he didn't find his name is because he had less than 200 reputation on Stack Overflow, at the time.  Now, I currently have more than 200 reputation on Stack Overflow; but for some reason, I can't find my name in the .

Ever since I changed my user account password, every time I log in to my machine I have to enter multiple passwords. First, I enter the new account password to actually log in. Once I'm at my desktop I get prompted to enter a few other passwords too. Namely the following:      My old password is required to successfully dismiss all of the above pop-ups. Is there some way of updating anything in my keychain that still uses the old password, to use the new password?  Any ideas what could have caused this? I can only imagine that the intended behaviour is for this update to happen automatically.

Obviously one of the things that this site encourages is the building up of reputation which is a reflection of how the community perceives you. However, after spending a while in any given tag, you can't help but get familiar with people by their SO user name and interpret their input accordingly. This is especially the case with comments: you have to click-through to the user's home page as their rep is not immediately visible.  Hence it's pretty confusing when certain users keep changing their names:    Is that someone who I have learnt to respect? Is that trollish behaviour, or has the user made a genuine error/comunication problem? Do I give this user the benefit of any doubt?   I must say that I find this is particularly the case on meta. I'm not suggesting that user-names should be permanently locked but perhaps there could be a limit to how often a name could be changed (e.g. no more than once per quarter year).

I don't understand this and I'm now worried as I have donated to a lot of servers and I don't want to lose this account. On the launcher it says my new username but when I log on it says "Account not Authenticated with minecraft.net" and "Non-Valid Username".  How can I regain the ability to use my account online?

I stupidly ran sudo chown -R carlos:carlos / and carlos is my user. This changed all files to be Carlos and I could not boot up again (because the root files were now owned by #1000) and I cant get sudo acess in live cd (because the owner of /usr was changed to my user). Can anyone help me? FYI I have mounted my hard drive.

I, too, am suddenly getting this message.  I don't see a Keychain First Aid option in Keychain, and the two Login Keychain Settings were already unlocked.  Any other ideas for what the error message is all about, and what I should do about it?

I just saw a user named: .yahoo.co.jpaqwsykcj3aulh3h1k0cy6nzs3isj  Could new users be named according to their user-number, or something other than "Unknown"? Perhaps User1234567 instead? It would be less awkward to address them in answers and comments.   Additionally, I often times have to check profiles to make sure users aren't abusing the system, since I find many of the same questions from "unknown (google)" from time to time. That, or I'll mistakenly think I've helped the user on a similar issue in the past, and assume the user has knowledge that he or she does not have.

In  I see from time to time the indicator kind of resetting itself. It does not know anymore that I already &quot;confirmed&quot;/&quot;noticed&quot; the new rep. Then I see something like this for instance:  or smaller numbers. But I am sure I did not gain any or so much rep since the last time I clicked on that number. This happens whenever I delete a post of mine. BTW my internet connection is excellent and the websocket connection is absolutely stable.

seems to be making edits to his own questions and saying that he's flagging them for deletion (not sure about the flagging part though since I don't have enough rep for that, but that's according to his newly edited questions. However according to his reputation - 10 currently - he shouldn't even have flagging privileges yet).  I stumbled upon one of his questions in the close queue, it had an accepted answer so I reverted the question back one step, and having seen that he's done the same thing to multiple questions I'm not sure about how this should be handled. I am not sure about if he has access to the delete button on his own questions or not.  As I'm not sure how to handle this I wanted to bring it to the community's attention and ask for support for how to handle future cases like this. Should all questions be reverted back? Should they be closed (possibly with the motivation "user seems to want this question gone")?

One of my friends just got hacked on her PC and her Yahoo account password was stolen. Now the hacker use her account under her name for bad reason. He may have change alternative email, security question, etc.  What can we do about that? We need her account back. Is it possible?   ps. I tried to google search for Yahoo contact information but I'm not sure where to knock Yahoo door.

I wanted to change my own password (as an admin) so I did the following command:  sudo passwd   and then it prompted for a password but when I tryed to relog, my password was not changed. I'm now wondering what password did I changed since it did prompted me to enter a password but I'm not sure what password did it changed exactly.  I know that if I do sudo passwd &lt;MY_USER&gt; it works, I'm just wondering without a user what happens.  Thank you
