Set a Custom Password During the Import Process

Create and enter a new password when Acrobat prompts you during the digital ID setup to secure the identity locally.

Acrobat requires a password to protect the digital ID and secure the signing process on your local machine. Even if the original P12 file is passwordless, you must establish a new password at the time of import or when applying the signature.

Open Adobe Acrobat and go to Edit > Preferences (Windows) or Acrobat > Preferences (Mac). Select 'Signatures' from the categories on the left panel.

Import the P12 File
