How to enable 2FA on Proton
- Sign in to your Proton account.
- Open Account settings → Security (the exact path varies; see the official docs link above).
- Choose your preferred method from the list — TOTP and hardware keys are the recommended options.
- For TOTP: scan the QR code with Kaito or your authenticator app of choice. Verify the first 6-digit code before saving.
- For hardware keys: insert your key when prompted and tap to enroll. Register at least two keys per account so loss of one doesn't lock you out.
- Save the recovery codes somewhere safe — they're your last resort if you lose your authenticator and your hardware keys.

- In Kaito, go to Tokens → New and add the Proton 2FA seed (or scan the QR).
- Permission the token to a group:
code-onlyfor most teammates,full-seedonly for the admins who would handle rotation. - Stream the audit log to your SIEM if you want a complete record of which team members generated codes for Proton and when.
