Proton Pass Secure File Attachments Explained

Proton Pass Adds Secure File Attachments — Encrypted Protection for Your Sensitive Data

Proton Pass, Proton’s encrypted password manager, has received a practical productivity upgrade: secure file attachments.

You can now save documents, images, spreadsheets, and other files directly alongside your passwords, notes, identities, and vault items — all protected by the same end-to-end encryption that secures your entire Proton Pass vault.

This update turns Proton Pass into a more complete digital vault for managing both credentials and the files that go with them.

What Are Secure File Attachments?

Secure file attachments let you store files together with specific items inside your Proton Pass vault.

For example:

• Attach a scanned copy of your passport to a government login
• Save insurance documents alongside portal credentials
• Store recovery codes with the relevant account

Each attached file is encrypted end-to-end, meaning only you can access it — not Proton, and not any third party.

Supported file types are broad, and storage limits depend on your Proton Pass plan.

Why This Matters

Password managers traditionally focus on logins and secure notes. File attachments extend this by keeping all related information in one encrypted place.

Before this feature, you might store:

• A login in Proton Pass
• A related PDF in a cloud drive

Those tools often use different security models. With attachments, everything stays under the same encrypted umbrella — reducing fragmentation and risk.

Who Gets This Feature?

Secure file attachments are available on paid Proton Pass plans, including:

• Pass Plus
• Pass Family
• Proton Pass Professional
• Proton Unlimited
• Other higher-tier or bundled plans

Note: Storage limits and attachment sizes vary by plan. Free plans may not include this feature.

Best Ways to Use File Attachments

Practical examples include:

• Attaching SIM account documents to telecom logins
• Storing encrypted backups or recovery codes with accounts
• Keeping identity documents with secure notes
• Sharing files securely alongside password entries

Attachments reduce app-switching and keep sensitive material organised and encrypted in one place.

You’re no longer limited to storing just passwords and notes. You can now keep credentials and files together, organised, and encrypted.

If you already use Proton Pass, this update significantly expands what your secure vault can do.
