1Password exports it's data as a '1Password Interchange Format', or 1PIF for short. This data format can be imported directly into the main 1Password application.
Note that this data format is unencrypted so be sure to keep it in a secure place and securely delete it when it is no longer needed.
To begin the export, enter your Master Password and then press the Export button.
You can choose to export all your data or just the items that have not been synced to the main 1Password application.
Exporting...
Below is your exported data formatted as 1PIF. Copy and paste this into a plain text document and save it to disk. You can then import the newly created file into the main 1Password application using the File > Import menu.
Remember this export is not encrypted. Store the file in a safe place and securely delete it once you no longer need it.
