Use Aster Mail over Tor

Aster runs an onion service, so you can reach your mailbox without your network provider seeing that you connect to Aster.

Before you begin

  • Install Tor Browser on desktop or Android, or Onion Browser on iPhone. Other browsers can’t open an onion address.
  • Create your account on the regular site first. Checkout and sign-up are turned off on the onion address.
  • Copy the current onion addresses from astermail.org/tor, and compare them character by character before you save a bookmark.

Sign in over Tor

  1. Open Tor Browser and connect.
  2. Paste Aster’s mail onion address into the address bar.
  3. Sign in with the address and password you already use.

Your mailbox, folders, and settings are the same account you reach on the regular site.

What changes on the onion address

  • Billing takes cryptocurrency only. To pay by card, sign in at app.astermail.org.
  • Storage, Invite friends, and Import are hidden in Settings.
  • Pages load more slowly, and security checks are stricter for Tor connections.
  • Outgoing mail still travels the regular internet once it leaves Aster. Tor protects the connection between you and Aster, not the delivery to a recipient’s provider.

Tips

  • Tor hides your network address, not your identity inside the account you sign in to. Keep a Tor session separate from identities you don’t want linked.
  • If an onion address stops working, check astermail.org/tor for the current one rather than trusting a copy from elsewhere.
  • For the strictest reading protections while you’re signed in, turn on Lockdown Mode. See How to turn on Aster Vanguard and Lockdown Mode.
