I have an offline password manager on my Android phone that isn't listed in the suggested password managers for the Proton Pass app for syncing the data.

I am personally using Password Safe, but it could be good to implement the following idea for this and other password managers that aren't listed or may be used on other devices.

I would like the option to copy the database file off of my phone (or other device) onto my computer, and then when asked to sync my password manager database, I can have the option to choose "upload existing database file" or something similar.

That way I can just upload a file to Proton Pass without having to sync an existing account if I don't have one or don't want to link them. That way I wouldn't have to manually copy them over or wait until I go to login to something and read from one password manager to put it into my Proton Pass.

I think it would also be good if there were an option for Proton Pass to read the database file and then allow the user to select "yes" or "no" on which credentials to sync, in case they don't want all of it to be uploaded - sort of like when you move photos in your phone's gallery app to another album.

Additionally, if it could identify duplicates or possible discrepancies.

Here's an example to clarify what I mean:

There are credentials/details to log into a certain site or account that is currently saved to the user's Proton Pass account.

When uploading the database file, it detects that the same email, phone number, username, etc. that is already in use with Proton Pass, so it notifies the user.

The user can then choose if they want to keep the Proton Pass details, the database details, save both, merge them, skip them or whatever else.

I imagine it working similarly to Microsoft Windows when the user attempts to copy a file to another folder and they are notified by a pop-up flagging the duplicate file and giving them options on how to proceed to avoid data loss or a mistake.

Thank you for taking the time to read my suggestion. I know there's a lot involved in this, but I think it would be very useful and would greatly increase the value of the Proton Pass application and enhance its features and simplify password management. I hope that you will consider it please.

P.S. Thank you to everyone at Proton for the services you provide. I am a big fan and love your work! :)
