解决登录问题
When sign-in fails, the message on screen tells you which fix applies. Find yours below.
For the regular steps on each platform, see Sign in to Aster Mail.
Aster asks for a security check
After several failed attempts, the sign-in page adds a security check and shows Complete the security check to continue. Solve it, and then sign in again.
If the check never appears or shows The security check could not load, a content blocker or a strict privacy extension is blocking it. Turn the blocker off for this site, or open a private window with extensions disabled, and then reload the page.
Sign-in is paused for your account
After 15 wrong passwords, Aster pauses sign-in to your account for 15 minutes. Your mail, settings, and devices are untouched. Wait, and then sign in with the correct password, or reset it at astermail.org/reset.
If you keep guessing, reset your password instead of trying again.
Sign-in is blocked from your network
After repeated failures from the same connection, Aster stops accepting attempts from that network for a while, and the pause gets longer each time it happens. To get back in sooner, switch networks, such as from Wi-Fi to cellular, or wait and try again later.
The two-factor code is rejected
- A code works once. If you see That code was just used, wait for the next code in your authenticator app.
- Codes depend on the clock. Turn on automatic date and time on the device running the authenticator app.
- After too many wrong codes, two-factor verification locks for about 15 minutes.
- To use a different method, select Use passkey instead, Use a backup code instead, or Use another verification method. Each backup code works once, and a 12-character code is current, while an 8-character one came from an older set.
If you have no second factor and no backup codes left, see Recover your account.
Your account is suspended
The page says Your account is suspended. Settings and new device links are turned off while a suspension is in place. Write to hello@astermail.org for the reason or to appeal.
The desktop device code doesn’t work
- The code expired. Select Get new code in the app, and enter the new one.
- This device is already linked to another account. Unlink it from that account first, and then link it again.
- Too many attempts. Wait about a minute, and then try again.
- The browser shows nothing after you enter the code. Go to
app.astermail.org/link-device, sign in, and enter the code there.
The sign-in page reloads or forgets you
- Allow cookies and site data for
app.astermail.org. Sign-in cannot complete when a browser blocks storage for the site. - Clear the site’s cached data, and then reload.
- Turn off Keep me signed in on a shared computer, and expect to sign in again each session.
If the page shows Your sign-in session expired, go back to the start and sign in again.
