Multiple Claude accounts with Proton Mail & SimpleLogin

This guide is part of Set up multiple Claude accounts — the full walkthrough for getting several Claude accounts so Power Claude can rotate between them.

Reliability: Reliable — privacy-first distinct addresses

Proton Mail (privacy-focused) and its sibling SimpleLogin create real, distinct aliases that forward to your inbox. Great if you care about privacy and want addresses no system will dedupe.

Works for rotation? Excellent. Proton/SimpleLogin aliases are real distinct addresses, ideal for separate accounts and privacy.

Step by step

1. If you don't have one, create a free Proton Mail account at proton.me.
2. Open SimpleLogin (built into Proton, or simplelogin.io) and click Create alias.
3. Pick a name for the alias, e.g. This email address is being protected from spambots. You need JavaScript enabled to view it.; mail forwards to your Proton inbox.
4. Create one alias per Claude account you want.
5. Sign up for Claude with the alias and verify from your Proton inbox.
6. Add the account to Power Claude's rotation.

Good to know

• The free Proton/SimpleLogin tier limits how many aliases you can keep; the cheap paid tier removes the cap.
• Aliases forward in; sending out from an alias is supported but optional for sign-up flows.

Pro tip: SimpleLogin lets you create aliases on the fly with a browser extension — handy when you're already on Claude's sign-up page.
