Retrieve admin password

Nextcloud version: 12
Operating system and version (eg, Ubuntu 17.04):

I cannot log into my nextcloud as I forgot my admin pw.
I use the nextcloud box and normally access it over wifi.

I remember setting up the email for retrieving the pw but it is not working.
Is there a way I can retrieve or replace it?

Thank you in advance for your help.

It should work with the command line tools occ.

If you connect via ssh, it should be something like:

sudo nextcloud.occ user:resetpassword username

Hello tflidd,

Thanks for your response. I haven’t yet had time to try it, but I’ll let you know if I manage.
