No username but still asks for password

[LiamFry]

Trilium Version

0.56.2

What operating system are you using?

Other Linux

What is your setup?

Local + server sync

Operating System Version

Debian 11

Description

I use both the web interface as well as the locally-installed client (with sync).
I was hosting Trilium on a spare server I had lying around my shop.
I moved it to a VPS, added TLS, and upgraded from 0.46.7 to 0.56.2
The web interface no longer prompts for username. According to #2679, multiple users are no longer supported; that's fine.
However, where does (did) Trilium get my password? Did I set it when I initially installed 0.46.7?
How do I change this password?

When I go to Options -> Password, I'm advised "... to remember your new password. Password is used to encrypt protected notes." Clearly, it's also used to login as ... some mystery user? Is this where I change the login password?

Hi, Trilium has always been single-user. The only change is that the username was removed, since it's useless in a single user app.

Did I set it when I initially installed 0.46.7?

Yes. Back then, setting the password was a mandatory step in the app setup.

How do I change this password?

Yes. There's only one password, and it's used to both login into the web interface and to encrypt data. I fixed the text to mention both things.
