Set or change the house-share password

Finder and File Explorer ask for a share password that is not always the login. Samba keeps its own copy. Set it once. Change it when you forget.

Finder and File Explorer ask for a password when they open the house folder. That password belongs to Samba. Samba is the program that serves the house folder. smbpasswd sets the password that phones and laptops use for that folder. It is not always the computer SSH login.

Skip until the share exists

If you never made the folder, stop. That is a file share on the computer. Finish that first. This note is the password step, including when you forgot it later.

What this is

You are setting the password phones and laptops type for the house folder. Not the login password that SSH asks for. Not the Pi-hole admin password. Not the router. The share password can match the computer Linux login, or it can be different. Samba keeps its own copy.

Set or change it from SSH

SSH from the couch the way you already do. Replace youruser with the computer username from install:

sudo smbpasswd -a youruser

The first time, this adds that user to Samba. If they are already there, the same command sets a new password. It asks twice. Nothing shows as you type. That is normal. Pick a password you chose. It can match the login, or it can be different.

Confirm

Open the share from a laptop the way a file share on the computer taught, or from a phone in open the house share from a phone. Use the share password you just set, not the computer SSH login unless you chose the same one. Laptop or phone still fails with the old password? Forget the saved house-share login. If the folder itself is gone, check the service and the firewall in when the house share disappeared, check the computer before you buy a NAS.

What next

Device still using the old password after this change? Forget the saved house-share login. Need a second person with their own login? Add another person to the house share. Someone should leave later: remove someone from the house share. When the folder fills, see if the computer still has room. If the share vanished, when the house share disappeared, check the computer. Skip exposing SMB to the internet. Skip a NAS for a password problem.

Skip
