Sign up
One account, the whole library.
Plinth runs on AthID — a single identity that works across the whole Athenium network. Sign up once and it works on Plinth, on Athenium-Marketplace, and on any service we or our partners run.
What to expect
About two minutes.
- 01
We'll take you to AthID.
AthID is where you actually set up your account — email, name, password. It's the shared sign-in for the whole network.
- 02
Fill in a few details.
Just your name and email to begin. Verifying your email is the longest part — usually a click on a link in your inbox.
- 03
Come straight back to Plinth.
Once you're set up, AthID brings you back here. You'll be signed in, with your library ready to fill.
Your data and identity stay with AthID, not with us individually. If Plinth ever shuts down, your account, books, and notes come with you.
