8 character limit in Screen Sharing password

I have Ubuntu 20.04.3, in two computers PC1 and PC2.

In PC1 I have

$ gsettings list-recursively org.gnome.Vino
org.gnome.Vino prompt-enabled false
org.gnome.Vino require-encryption false
org.gnome.Vino use-alternative-port false
org.gnome.Vino disable-background false
org.gnome.Vino disable-xdamage false
org.gnome.Vino alternative-port uint16 5900
org.gnome.Vino icon-visibility 'client'
org.gnome.Vino authentication-methods ['vnc']
org.gnome.Vino network-interface ''
org.gnome.Vino notify-on-connect true
org.gnome.Vino mailto ''
org.gnome.Vino lock-screen-on-disconnect false
org.gnome.Vino use-upnp false
org.gnome.Vino vnc-password '<12-char string>'
org.gnome.Vino view-only false

In PC2 I have the same, except for

org.gnome.Vino vnc-password 'keyring'

And when I try to set the password in PC2, Settings -> Sharing -> Screen Sharing, I am limited to 8 characters. The usual case I met, e.g. in PC1, is not having such limit.

How can I change this?

It seems to be a string

$ gsettings range org.gnome.Vino vnc-password
type s

but I don't dare simply setting the value.

I understand this is a limitation of VNC. It only checks the first 8 characters of a password. You get around this by using VNC through ssh tunnel. The ssh is more secure.

@user68186 - I missed that! Still, how do you explain the difference in `org.gnome.Vino vnc-password`? And how to change that? I am not sure that is part of the cause for [this](https://askubuntu.com/questions/1380183/vnc-via-ssh-tunnel-working-or-not-unkown-causes).

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
