You want to change your own password — typically right after first-boot.

Steps

1. Click the cog icon top-right → you are in the settings.

2. Pick Profile in the left sidebar.

3. In the Change Profile Details form enter a new password and confirm it in the second field.

   

4. Optional: also change the username.

5. Click Save Profile Changes.

On the next login use the (possibly new) username and the new password.

Notes

• Once you set a custom password, it is no longer derived from the machine ID — you alone are responsible for it from then on.
• If you lose your password, a user with network-configuration (or other admin) permission can set a new one in Settings → Manage Users.
• If access is fully lost, Brinkhaus personnel can always re-derive the initial password from the machine ID.
