What problem are you trying to solve?
Sending securely users credentials at sign up, such as password and activation letter for 2FA, via password encryption, through user property field of the final PDF and send it through email.
Why is this an issue for you?
sending letters may take longer time, however sending credentials through email should require an extra layer of security.
What solution do you suggest?
in the plugin com.airlock.iam.core.misc.renderer.saveaction.PdfSaveActionConfig add the password feature for the pdf, that can take the user property such as document id, birthday or whatever to save the pdf.
com.airlock.iam.core.misc.renderer.CredentialSecretGenerator can have the property for sending through email the credentials, which can appply to either passwords, or letters.
