Frequently asked questions
Which password do I need?
This is the open password — readers will need it to open the file at all.
Can I remove the password again?
Yes, use the unlock flow with the same password to get the plain file back.
Is my password sent anywhere?
No. The password never leaves your device; encryption also happens locally.
