Toggle default save signed document history
We should be able to choose the Default action (Toggle) if we want to-be-signed documents to autosave to Adobe account and/or choose on demand for any particular document. Currently, everyone using that Adobe account has access to any files ever sent/received to-be-signed over however many past years. That may include documents with confidential information. Potentially confidential files from past employees/employers, past students/teachers, past friends/family to whoever currently has access to the Adobe account.

Hello Joel,
Thank you for your suggestion! We appreciate your interest in helping us improve. We are always looking for ways to improve our product and will definitely consider your request.
As a workaround you can always use the "Send in Bulk" tool, which does have a password protection, just follow the next steps, and also check the video attached:
- Use any entry point named "Send in Bulk" and add the desired file to be sent
- Add the required recipients
- Add an access password under "Agreement settings"
- Modify the document with as many fields as needed
- Send the agreement
This way, in your account, your document is protected from anyone who does not have the password.
