Set up a new vCenter Server a while back and didn’t write down the password. Guess what happened next, trying to find a way to reset both of them.
Here is what I managed to do.
First of all, reset the “root” password.
Log in to the ESXi host that powers the vCenter Appliance and do the following steps:
- Open the vCenter Console and reboot it.
- Press the “e” key right after the VCSA Photon OS start to enter the GNU GRUB Edit menu.
- Add the following line at the end of the line that starts with the word “linux”.
- Press F10 to continue booting once done.
- Then run the following commands
mount -o remount,rw / passwd unmount / reboot -f
Now go to https://serverip:5480/ to access the vCenter Server Appliance using the new password.
Now, let’s reset the Single Sign-On Password:
Log in vCenter Server Appliance to enable SSH and then log in as the root user via SSH.
Run the following command to enable access to the bash shell.
set --enable true
Type “shell” and press enter. And then run:
Press 3 to enter the Reset Account Password option to generate a new temporary password that you can log in to vCenter Server. From there, you can change the password to whatever you want.
