How can I reset the VCSA root password if I only know the SSO password?

Problem:

The VCSA root password is not working but the SSO password is

Solution:

1. Connect SSH to VCSA 6.7 and login using administrator@vsphere.local where vsphere.local is your default SSO Domain. ​​​​​

2. Run the below commands:

shell.set --enable true
shell

3. Run the commands:

sudo -i
passwd

Now reset the password
