FAQ: signatures
Information for current SwissID App users
Why am I prompted to switch to the SwissSign Wallet instead of the SwissID App?
The signature service has been completely redesigned and is now available as an even more convenient web-based solution. As part of this enhancement, digital signatures are newly to be confirmed with the SwissSign Wallet, offering a more lightweight alternative to the SwissID App. Please note that the SwissID App will be discontinued as of 1 October 2025.
I have downloaded the SwissSign Wallet, how can I start using it?
The SwissSign Wallet is used solely to securely confirm your digital signatures as part of the process to confirm a signing request. As such, the SwissSign Wallet does not offer standalone features for signing.
When you sign with a Qualified Electronic Signature (QES) for the first time, you’ll be guided within the signature process to download and set up the Wallet. After setup, the Wallet is only required when confirming your QES signatures.
To confirm a signature, either scan the QR code displayed in your desktop browser or tap Confirm in App when using your mobile browser. Both options will redirect you to the SwissSign Wallet, where you can securely approve the signature using your biometrics.
I have downloaded the SwissSign Wallet, but cannot see my documents?
The SwissSign Wallet is used solely to securely confirm your digital signatures. To view your documents, simply log in to the signature service via sign.swissid.ch, which is newly also conveniently available on your mobile device.
