The app is compatible with any Android device running version 15 or higher and any web browser.

To sign, you must install at least one recognized digital certificate from a PKCS#12 or PFX (Personal File Exchange) file in the app. Follow the instructions in the app's help for how to install it. You can obtain a certificate in PKCS#12 or PFX format from a certification service provider.

The app can be invoked from a compatible website for electronically signing a web-based transaction, or opened directly from the icon on your Android device for signing PDF documents accessible from the device (local or cloud storage). You can verify proper operation when invoked from a web page by using the following test web page: valide.redsara.es/firmaMovil/demo.html

You can find more information about the Autofirma App on the e-Government Portal website of the Ministry for Digital Transformation and Public Service (administracionelectronica.gob.es/) and in the Technology Transfer Center repository (github.com/ctt-gob-es/firma-ios).
