No, none of the passwords used in a Linux system can be "recovered" because there isn't a reverse encryption for it.
However, you can "reset" the root password by using the single-user mode at boot time (which puts you in the root account automatically) and then changing at that time.
The password would be whatever the root password is set to.
You can't recover passwords in Linux; you can only reset the passwords on various accounts.
In Linux and Unix-like systems, the "root" account is the only account with all possible privileges. The "root" password would be the password needed to access this account or assume its identity.
Run the command "passwd". You will have to enter your old password to change it. If you are root, you will not have to enter the old password to change a user's password.
Try "root" as the username and "uClinux" as the password.
Linux Mint, like Ubuntu and most other Debian-based distros, do not enable the root account by default. If you need root permissions to do something, enter the commandsudo [whatever program you want to run]and enter your password when prompted.
When it askes for user enter root, and then when it asks for password enter the password. If you don't know password for root it's a really serious problem. You can also log in as root via command line by typing "su"
You can obtain root permissions in Linux by using the "sudo" command before executing a command that requires elevated privileges. This allows you to temporarily act as the root user to perform administrative tasks. Alternatively, you can switch to the root user using the "su" command by entering the root user's password.
the sign for root partition in linux is : /
You click forgot password and they send your password to your email
go to a site which know sbout to recover username and password
have a look @ http://en.opensuse.org/Recover_Root_Password you will need a install media (boot CD or DVD) for the (open-)SUSE version you want to recover the root password from in fact, RECOVERING is not the right word, here; the only way to recover it is to have it written down somewhere or someone else remembering it (still); otherwise, you are down to RESETTING the root password. boot the system from the install media by choosing RESCUE (type F2 / F3 / F4 / F5 in the boot menu to see which option does that; Linux rescue is a good bet). once finished booting, you have to make your server / workstation's root partition the current root; 1st determine which is the root partition of your server; $> ls -l /dev/sd* will show you all (e-)sata and usb devices and the partitions thereon. some newer motherboard also show ATA disks here; otherwise you will get list of ATA devices with $> ls -l /dev/hd* for other devices like (external) RAID, if you don't know which device it is, start the install (just hit the enter key without typing in Linux rescue) and choose ADVANCED partitioning. this will show you all the available disks & there partition. once you know which partition is the root, follow «CD/DVD Recovery Mode» from above link
