このガイドを信頼する理由

I’ve been using Proton Pass as my daily パスワードマネージャー for over a year.

Every step here comes from my own screen, not a press kit.

Proton Pass is a free password manager built by the Swiss team behind Proton Mail.

Most people install it, save a few passwords, and stop there.

That’s a shame, because the aliases and monitoring tools are the best part.

This beginner’s guide shows you how to use Proton Pass properly, step by step.

Proton Pass Tutorial

This tutorial walks through every feature in order, from first install to the tricks power users rely on.

プロトンパス

Stop reusing the same password everywhere. Proton Pass locks your logins behind end-to-end encryption and hides your real email with aliases. The free plan is genuinely useful — no credit card needed to start.
