Updated January 2026.
Searching for a temporary ProtonMail address usually means you want a privacy‑friendly email you can use for signups without exposing your “main” inbox. The key thing to know: Proton Mail doesn’t provide a one-click “temporary ProtonMail generator” that creates a brand-new @proton.me inbox that expires automatically.
But you still have several good options, depending on your goal:
- For one-time OTP codes or low-stakes signups: use a disposable inbox like Anonibox temporary email generator.
- For accounts you might keep (password resets later): use a recoverable alias strategy.
- For separation inside Proton: use additional addresses/aliases (plan-dependent) or a second inbox.
Quick answer: the best way to get a temporary ProtonMail address
Use this decision tree:
- Need a throwaway address for an OTP code right now? Use a disposable inbox: Anonibox.
- Need privacy AND account recovery later? Use an alias strategy (recommended): Email Alias (2025).
- Want separation but still keep everything in Proton? Use Proton’s additional addresses/aliases (plan-dependent) or create a second Proton inbox.
- Getting blocked or not receiving verification emails? Jump to the troubleshooting checklist below.

What people mean by “temporary ProtonMail address”
Most people aren’t literally looking for a Proton inbox that self-destructs. They’re trying to achieve one of these outcomes:
- Spam protection: keep marketing lists away from your main inbox.
- Compartmentalization: separate “signups” from personal email.
- Privacy: avoid sharing your primary address everywhere.
- One-time verification: receive an OTP code, then move on.
- Recoverability: still be able to reset passwords later.
The right tool depends on whether you need recovery later. Disposable inboxes are best for one-time tasks. Aliases are best for privacy + recovery.
Option 1: Use Proton Mail aliases / additional addresses
Proton Mail can support multiple addresses and/or aliases in a single mailbox (exact availability depends on your plan and configuration). This option is ideal when you want a “temporary-feeling” address that is still recoverable—so password resets and support emails keep working.
Best for
- accounts you might keep
- services that block disposable email domains
- clean separation (“shopping”, “newsletters”, “apps”, “trials”)
Downsides
- Not unlimited “one-time” addresses by default
- Still tied to the same core mailbox identity
Tip: If you want a scalable long-term system (one address per site, with the ability to disable any one address), an alias strategy is often better than relying on one mailbox alone: Email Alias (2025).
Option 2: Use an alias service for “per-site” addresses
If your goal is “every site gets its own unique email address,” you want an alias approach. The workflow looks like this:
- Create a unique alias for each website (e.g.,
netflix@your-alias-domain,discord@your-alias-domain). - Forward those messages to your mailbox (Proton or any other inbox).
- If one alias leaks or gets spammed, disable it without affecting your other accounts.
This solves the biggest weakness of disposable email: recoverability.

Option 3: Create a second Proton inbox (separate mailbox)
If you want full separation—different login, different mailbox, different rules—creating a second Proton account can work well (especially if you want “signups only” separate from personal mail).
Pros
- True separation (no mixing)
- Recoverable long-term
- Often accepted on sites that block disposable domains
Cons
- More inboxes to manage (security, 2FA, cleanup)
- Becomes a long-term identifier if reused everywhere
- Slower than disposable email for one-time OTP codes
Best practice: treat the second inbox as “signups only,” enable 2FA, and use a password manager.
Option 4: Use a disposable inbox for one-time OTP codes (fastest)
If you only need an email for a quick code or confirmation link, a disposable inbox is usually the fastest tool.
Start: Anonibox temporary email generator
Best for
- OTP / verification codes
- download links (“email me the file” gates)
- low-stakes signups you don’t plan to keep
- quick access flows (Wi‑Fi portals, giveaways)
Not recommended for
- banking, healthcare, government portals
- paid subscriptions, invoices, receipts
- any account you might need to recover later

Proton aliases vs second inbox vs disposable inbox
| Option | Best for | Recoverable? | Privacy level | Common downside |
|---|---|---|---|---|
| Proton aliases / extra addresses | Recoverable separation | Yes | Medium–High | Availability/features depend on plan |
| Alias strategy (per-site) | Privacy + recovery + control | Yes | High | Requires setup/discipline |
| Second Proton inbox | Full mailbox separation | Yes | Medium–High | More inboxes to manage |
| Disposable inbox | One-time OTP codes | No | High | Some sites block disposable domains |
What to do when a website blocks “temporary” email
Two common failure modes:
- Hard block: “Invalid email” immediately after entering it.
- Soft block: email is accepted, but the verification email never arrives.
Use the clean playbook (no “bypass hacks”):
- If you might keep the account: use an alias or a standard mailbox you control.
- If it’s low-stakes: try a fresh disposable address and resend once.
- If it keeps failing: switch from disposable email to an alias strategy.

Troubleshooting: verification email not received
If you’re using a disposable inbox (or any “temporary” address) and the verification email isn’t arriving, do this in order:
- Wait 60–90 seconds. OTP emails can be queued.
- Resend once. Avoid repeated resends.
- Keep the inbox tab open. Mobile background tabs sleep.
- Try a new address. New signup → new inbox.
- If it still fails: assume blocking → switch to an alias.
