Is A-Trust down right now?
The A-Trust status here tracks users whose activation code fails, whose TAN never lands or whose app will not sign. Fresh A-Trust down reports often spike when a big portal changes its login and crowds rush to reactivate. One blocked attempt after wrong entries is a safety lock, not an outage.
The pieces fail apart. The website can run while SMS delivery lags, or the app can sign while the activation page stalls. A real A-Trust outage stops codes, TANs and signing in the same hour.
Is A-Trust down for me or everyone?
Separate the three pieces before you judge. Open the website, then test the app, then ask if an SMS from any service reaches your phone. When the site loads and only your TAN lags, the fault sits in delivery or your number. Reports here show if activations fail across networks at once.
How does app activation work on the A-Trust website?
The activation page starts on a second device like a computer. You enter your phone number and signature password, get an SMS TAN and type it in the browser. The app on your phone then shows a ten digit activation code that you copy into the browser page.
Each step waits on the one before. Restarting the whole activation gives a fresh pair of code and TAN that belong together.
What can you do inside your A-Trust account?
The account shows your certificates and lets you change your signature password. You upload documents there and sign them as PDFs with your signature. Past signed documents and their state sit in the same account.
When does the A-Trust signature app demand a reset?
A new phone, a restored backup or a forgotten app PIN breaks the app link to your identity. The app then asks for a reset and a fresh activation from the website. That demand is a safety rule, since the signing key lives on the device itself.
Does A-Trust still support the switch from Handy-Signatur to ID Austria in the app?
Yes, the app profile tab shows the switch button for registered users. It upgrades a fully registered Handy-Signatur to ID Austria with full function, or to the basic function when the registration was lighter. The switch runs inside the app without a new activation code.
Common A-Trust Problems and Fixes
A-Trust faults sit in the code pairing, the TAN delivery or the app link. These checks rebuild the chain link by link.
Restart the activation for a fresh code pair
Close the activation page and the app, then start the activation again from the website. A fresh run issues a code and a TAN that belong together. Mixing steps from two runs is the classic activation failure.
Type the TAN while it is fresh
The SMS TAN lives for a short window only. Keep the phone beside the computer and type the code at once. A TAN from an earlier attempt no longer counts, even when it looks the same length.
Reset the app when the PIN is lost
Open the app settings and use the reset inside the app. After the reset, run the website activation again to link the app. Guessing the PIN locks the app after a few tries.
Check the stored phone number
TANs go to the number in your account, not to the SIM in your hand. After a number change, update the account first through the route the account page offers. An old number explains most missing TAN reports.
Turn off the phone backup before a reinstall
A restored app backup can carry a broken identity link. Delete the app, switch its backup off and install it clean. Then activate once from the website and let the fresh link settle.

Frequently Asked Questions
What do I need for the A-Trust app activation?
You need the app on your phone, a second device with the activation page, your phone number and your signature password. An SMS TAN and a ten digit app code pair the two.
How long does an A-Trust SMS TAN stay valid?
The TAN counts for a short window after the SMS lands. Type it at once in the browser page that asked for it. A late TAN fails even when typed right, and the page issues a new one.
Is A-Trust down or is my activation pair stale?
Restart the activation once for a fresh code and TAN. A working fresh run means your old pair expired. Reports here show if codes and TANs fail for users across networks today.
Does the A-Trust app work after a phone change?
The signing key lives on the old device, so a new phone needs a reset and a fresh activation. The website activation page links the new app in minutes. Your account and certificates stay the same.
Can I sign a PDF inside my A-Trust account?
Yes, the account takes document uploads and signs them with your signature. Signed files wait in the account for download.
Where do I change my A-Trust signature password?
The account settings hold the password change with your current password as the key. Pick a password you can type fast during signing. The app asks for it when a signature needs approval.
