SPASS Converter

The fastest way to migrate from Samsung Pass to Google Password Manager — decrypt your .spass export on-device, get a ready-to-import CSV in seconds. Your passwords never leave your phone.

Samsung Pass lets you export your saved passwords as an encrypted .spass file — but no standard password manager can open it directly. SPASS Converter decrypts the file on your phone using your Samsung Pass password, then produces a CSV you can import straight into Google Password Manager / Chrome, Bitwarden, 1Password, KeePass, or any tool that accepts the standard CSV format.

Nothing ever leaves your device. Every network permission is explicitly blocked at the manifest level.

FAQ

How do I import Samsung Pass passwords into Google Password Manager?

Export from Samsung Pass (Settings → Export passwords) → convert with this app → import the CSV at passwords.google.com → Settings → Import passwords. The CSV column format matches exactly.

How do I open a .spass file?

A .spass file is an AES-256 encrypted export from Samsung Pass. You cannot open it with a text editor or spreadsheet. Use SPASS Converter to decrypt it on your device and convert it to a readable CSV.

Does this app upload my passwords anywhere?

No. The app has no internet connection at all — every network permission is explicitly removed in the manifest (tools:node="remove"). Decryption and conversion happen entirely in memory on your device.

What's the Samsung Pass export password?

It's the password you use to unlock Samsung Pass itself — not your Samsung account password. You set it when you first configured Samsung Pass.

Can I import into Bitwarden instead of Google?

Yes. In Bitwarden's web vault go to Tools → Import data → select Google Chrome (CSV) as the format, then upload the CSV. The column layout is compatible.

Can I import into 1Password?

Yes. Use 1Password's built-in CSV import (File → Import → 1Password or Generic CSV). You may need to map columns during import.

Does it work with Samsung Pass app passwords (android://)?

Yes. App passwords stored in Samsung Pass use android:// URIs. SPASS Converter includes a resolver for 100+ common Android package names (Instagram, WhatsApp, Netflix, Spotify, Cash App, etc.) that maps them to real website URLs automatically.
