A safer path between password managers

Apple and Google already provide import tools. PortaPass makes the sensitive file legible before you hand it to them.

1

Open locally

Choose a CSV on your device. A 25 MB and 10,000-row ceiling prevents unexpectedly large files consuming memory.

2

Review precisely

Map columns, inspect row errors, separate exact duplicates from conflicts, and exclude individual entries without exposing passwords.

3

Export deliberately

Create the destination format, preserve Apple OTPAuth values, respect Google’s 3,000-row limit, import, then delete both files.

Safe browser tool

Check a CSV header—never the password rows

Paste only one line of column names. Checks run in this tab, with no upload. Malformed quotes, duplicate names and hidden line separators are flagged. A matching header does not prove that the full file will import.

Never paste usernames, passwords, notes or OTPAuth values into a website. Use the PortaPass app for full local analysis.

Input is never submitted or stored. It is cleared after a check, when you change destination, or when this page leaves the foreground.

Your result will appear here. No file or password rows are checked.
