Same problem here with the only difference that we use the key cookie to (automatically) authenticate the users as mentioned here.

B.t.w., I searched the docs and neither the environment variables PASSWORD or HASHED_PASSWORD, nor the authentication cookie key are mentioned anywhere. The environmental variables are mentioned in code-server --help but not the cookie. Should these things be documented or are they subject to changes?

Oh, looks like the authentication cookie was renamed (again) in #4548 to code-server-session.
Setting the hashed password using the new cookie works as before. Tested for 4.0.0 and 4.0.1. I still wish this method had been documented.

I checked as well and don't see them. Very strange. I thought we had docs on this but I guess not. Thanks for raising this!

Ah, I forgot that happened. Yes, you shouldn't have to go digging to find this. Thank you for testing! Where would you expect to find this information in the docs?
