AltF Vault

Import passwords from a CSV file

Export your passwords as CSV from your browser or password manager, then import the file in the Backup tab. AltF Vault recognises the column names used by Chrome, Edge, Firefox, Safari, Bitwarden, 1Password and LastPass, skips duplicates, and encrypts everything on your device. The CSV is never uploaded. Delete it afterwards.

Import passwords from a CSV file: questions and answers

Is my CSV uploaded?

No. The file is read by the page in your browser, turned into encrypted items and discarded.

What columns are needed?

At least a password or notes column. Name, URL and username are picked up when present, along with favourite and folder or tag columns.

Will importing twice create duplicates?

No. Rows with the same site, username and password as an existing item are skipped.

Can I export back to CSV?

Yes. The Backup tab can export logins as a plain CSV in the common name, url, username, password, note format, after a clear warning.
