If I restore a previous config, will it change the admin password?

Hi,

I did some experiments and messed up my config, but I still have access to the router through the web interface. I have an old-ish backup with a stable config, and I wanted to restore it.

My problem is that I don't remember the admin password I was using when I first made that backup, as I changed it some time ago. I'm afraid that after the restore the password might revert to an older version I can't remember, and I would lose access to the router.

So here's my question: when we restore from a backup, does that change the admin password too? or is it left as is?

I realise that in the worst scenario, I could always reset to factory defaults and rebuild the config from scratch, but in that case, I might as well try to fix the config from its current state, at this point I'm not sure which of these would entail more work. Still, if I were able to restore from the backup without fear of it changing my password, that would be the best way.

Thanks!
