My password is like a brick wall reinforced with steel bars. I have written it down manually and type it in manually every time I use it. It's over 100 characters long. Special characters, capitals letters and numbers are all included. Its a randomly generated password.

Am I in risk of losing more data? my understanding they would need to still bruteforce the password because its not stored in plain text in the database. Which being realistic is almost impossible and would take hundreds of years.

Should I change my password?

Yes. build another brick wall. The attacker(s) have a salted copy of your password and it ain't made of brick.  Smiley

imho is just good practice to change password. even they were somehow crypted and you are using this big ass long phrase, it takes few minutes and better safe then sorry..

you are writing down manually over 100 characters every time you used it? such paranoia..

Yes. Especially if you use the password for other sites as well.

Which being realistic is almost impossible and would take hundreds of years.

Realistically speaking? It would take quadrillions on quadrillions of years for the average bruteforcer.

It's over 100 characters long. Special characters, capitals letters and numbers are all included. Its a randomly generated password.

Why?
If what you say is true, your password should be safe.

Code:

bitcointalk.org passwords with current technology

s=second; m=minute; h=hour; d=day; y=year; ky=1000 years; My=1 million years

...

How did you ensure it's random? If you used software then it might not be properly random. You need to use dice or a random number generator to make it properly random.

Get a password generator then you'll never have to remember or type it in. And can change it as often as you like with no consequences on your end.

Can you tell more details about the password generator you are taking about?

You could use the free password manager keepass2, it has a built-in password generator:

What if keypass goes down?  I added one of my passwords to a password manager site and then later I couldn't log in.  A trojan in your computer could read a passwords.txt file and then upload it to a command and control server.  If you put it into the browser, it really is the same problem.   Ultimately, a trojan could keylog your password in.  I had a ten character password and according to grc's password haystack's page that was two weeks of super computer hacking.  Now, considering everytime you add an interesting character you multiply the time it takes by the key space, one hundred should be more than enough.

I copied the 63 random ASCII printable characters at the password generator at www.grc.com and put it into the password haystack's page at the same domain and got this for a massive offline super computer scenario:

1.27 hundred thousand trillion trillion trillion trillion trillion trillion trillion trillion centuries

P.S.: The reason for changing frequently though is so in case your plain text password gets out, the attacker will lose control of your account as soon as you change your password.

You should read up on the security on some of the password managers, it's pretty impressive, but nothing is perfect. The entire database is encrypted, typing the master password supports Secure Desktop, and the autotype functionality also fools most keyloggers with Two Channel AutoType. Also supports two factor with a master file, which can be on a USB stick or wherever else.

This.

And: don't forget that keepass is open source. You can fetch the source files, inspect the code and build your own keepass.exe!

You'll need to make sure to be careful of cheeky gecko squad members trying to DDoS your password, really you should be preparing your password security about 36-48 months before conception if you want any real chance of being able to have a secure password. Based on that, I think you have to change your password unfortunately.

In all seriousness in case someone tries to mug me for having a joke, no.

OP, sorry for hijacking your thread, but I need some opinions.

I store my passwords in a text file (over three hundred passwords) in a non-OS drive on my PC.
I usually just copy paste when logging at any site, so I don't think I should worry about keyloggers, right?
My password is a random 8-15 characters alphanumeric+symbol combo, so that's pretty secure, right?
Trojans typical only focuses on OS drives, right?

Some keyloggers can read the information in your clipboard. If you want to reduce the effectiveness of some  of these keyloggers, you should probably opt in for using a password manager. Keepass has a Two Channel AutoType feature, which can avoid some problems with keyloggers, however not all. It's a much better approach than your current method.

Thank you Welsh.
One follow up question. How easy is it to compromise Keepass? Are there, and would there be, trojans capable of extracting data from Keepass, and does it communicate/send saved passwords to a server somewhere?
Sometimes I wish retinal scanning tech or something along that lines becomes widely adopted and we can completely dispense with passwords. Smiley
