I was trying to log into my account at Cosmology"home but I couldn't - due to an SSL error on their website.
BUT: On their message board is a solution, THAT WORKS !!

Grateful thanks to "muzzdiez" on their messageboard for posting the above.I figured out how to fix that if you have at least one BOINC client you have this project attached to.
1. Open the file named "account_www.cosmologyathome.org.xml" in your BOINC data directory (C:\ProgramData\BOINC, /var/lib/boinc, etc.) in a text editor.
2. Find the line that looks like this:
<authenticator>1234567890abcdef1234567890abcdef</authenticator>
Let's call whatever you have in the place of "1234567890abcdef1234567890abcdef" the authenticator.
3. Open http://www.cosmologyathome.org (note http://, not https:// in the beginning!) in your browser
4. Open the browser console (usually F12 for Firefox, idk for Chrome/other browsers - (says Timbo: I use Brave and F12 works !)
5. Switch to "Console" tab
6. Insert the command and hit enter:
document.cookie="auth=1234567890abcdef1234567890abcdef"
Here, replace 1234567890abcdef1234567890abcdef by your authenticator you found in the step 2.
7. Reload the page. Voila! Now you're logged in.
I just leave it here in hope this manual might be helpful for those who are still have their BOINC clients attached to this project.
