Password reset or recovery

[tessa]

Hi. I set aside my Pinebook Pro (with the default Manjaro) for a year while I was working on other things, and in the meantime I forgot my password. I don't have it set to require a password on boot, so I can get into the computer. But I can't perform any sudo commands or run the updater.

How can I get this to work?

Thanks,
Tessa

Can you boot from uSD?
If so, mount emmc, (lsblk to get right device node),
go to /mount-point/etc, edit shadow (you will need to be root, on uSD boot)
each line is an entry, fields are separated by ":"
the 2nd field is hashed password, about 60+ chars
so, for root what you want (for no password)
root:: .....and so on
IOW, make the 2nd field empty

Thanks! I'll get a uSD and give it a try.
