Need some guidance with the TPsign app?
TPsign is designed to deliver eIDAS-compliant electronic signatures supported by qualified trust services. This App Guide section is intended to answer the most frequently asked questions about using the app.
If you need further assistance, you won’t be left on your own. Our expert support team is available to guide you through the signing process, identity verification, and the use of qualified certificates and time stamps—ensuring your documents remain legally valid and trusted across the EU.
The TPsign app allows you to sign documents directly from your smartphone. Available for both iOS and Android, it complements the TPsign desktop client (Windows and Apple) and the web platform.
Sign on Any Screen
Using the same credentials, you can sign seamlessly from your mobile device, your workstation, or via the web. Due to the limited screen size, the TPsign app does not support the management of signature graphics or column layout and may present minor layout variations. However, it allows you to sign documents in the same formats as the desktop client and web versions, and it supports the same features, including multiple signatures, multi-document signing, and time stamping.
It is advisable to use the TPsign app for its primary purpose:
signing documents on the go
