Mandatory use of the electronic ID (eID) for signing the application

1. What is the eID in the digital context?

The eID feature is based on a secure chip embedded in your ID card or residence permit. This function is usually activated automatically if the document was issued after 2017.
The chip enables you to prove your identity electronically, for example by using the AusweisApp, and provides secure online signing capabilities (ausweisapp.bund.de).

2. Qualified Electronic Signature (QES) and European standards

Under the eIDAS Regulation, you can create a qualified electronic signature (QES) remotely, without the need for a separate physical signature card (personalausweisportal.de).
The new ID card (nPA) supports a chip with digital signature technologies. You can purchase a qualified signature certificate from a certified provider, link it via the eID function, and then use it to sign documents such as PDF files in a legally binding way (personalausweisportal.de).

3. Technical requirements for signing via the naturalization portal

To complete an electronic signature on the citizens’ portal (including the naturalization application), you must have:

• an electronic ID card or residence permit with activated eID function,

• a 6-digit PIN, which can be set or changed via the AusweisApp or at the Bürgeramt (ausweisapp.bund.de),

• the AusweisApp installed on your smartphone or the computer you are using (ausweisapp.bund.de),

• a NFC-enabled smartphone or a USB card reader that works with the AusweisApp.

4. Steps for the electronic signature

1. Complete your application in the Einbürgerungsportal until you reach the signature page.

2. Select the option “Electronic signature using eID”.

3. You will be redirected to the AusweisApp: place your ID card on the device or use your smartphone as a reader, then enter your PIN.

4. The document is electronically signed, and you are redirected to the portal with a digitally verified confirmation.

5. Your application is formally submitted with a qualified signature code, which removes the need to submit an additional paper version.

5. Why is this step important?

• It provides a legally qualified electronic signature (QES) with a high level of trust, recognized by courts in Germany and across the EU.

• It significantly reduces paper-based procedures, such as printing, manually signing and scanning forms.

• It ensures data integrity, reliable transaction documentation and an enhanced security level, in line with modern legal requirements.

6. Points to keep in mind

• The eID function must be activated: this can be done in advance or later through the Bürgeramt if it is currently deactivated (stmi.bayern.de, allaboutberlin.com).

• Your PIN must be set and remembered; it is required for every signature process.

• The AusweisApp and the signature confirmation should be obtained only from the official website, and are usually provided in German or English.
