Temp Mail for OTP Verification
Generate a disposable inbox, paste it into a signup form, and copy the one-time code when it arrives. TempMailGrab highlights OTPs automatically so verification is fast and private.

Why OTP flows need a better temporary inbox
Most sign-up pages now send a code instead of a simple link. That makes the inbox experience matter: you need the message to arrive quickly, the code to be easy to find, and the address to stay alive long enough for a retry.
TempMailGrab is built around that flow. Incoming messages are parsed as they arrive, common one-time passcodes are highlighted, and verification links are extracted so you do not have to open every HTML email by hand.
How to use temp mail for OTP
- Open TempMailGrab and copy the generated temporary email address.
- Paste it into the service that is sending an OTP or confirmation email.
- Wait for the message to arrive in the live inbox.
- Copy the highlighted OTP code or open the extracted verification link.
- Delete the inbox when finished, or let it expire automatically.
When not to use it
A temporary inbox is the wrong tool for permanent accounts, banking, government services, paid subscriptions, account recovery, and long-term two-factor authentication. If losing access later would matter, use an email address you control permanently.
Some services block disposable domains. If a site rejects temporary email, use a permanent address for that service.
Why TempMailGrab is useful for verification
- OTP extraction: codes are shown as structured fields instead of hidden in message text.
- 24-hour default inbox: slow or retried verification messages still have time to arrive.
- Real-time delivery: the inbox updates while you stay on the page.
- No signup for web use: create a temporary address without giving personal details.
- Developer API: automate the same OTP flow in Playwright, Cypress, and CI.

Automate inboxes with the API
Prefer to script it? Generate disposable inboxes and read auto-parsed OTPs & verification links programmatically — built for QA, test automation, and bots. The same private inboxes, over a clean REST API.
# 1. Create a private inbox
curl -X POST https://tempmailgrab.com/api/v1/inbox \
-H "Authorization: Bearer $TMG_API_KEY"
# → { "id": "inb_…", "address": "a1b2c3d4e5f6@tempmailgrab.com" }
# 2. Poll for mail — the OTP + verification links are auto-extracted
curl https://tempmailgrab.com/api/v1/inbox/$ID/messages \
-H "Authorization: Bearer $TMG_API_KEY"
# → { "messages": [{ "extracted_otp": "123456", "extracted_links": [ … ] }] }Related guides
Frequently Asked Questions
Can I receive OTP codes with temporary email?
Yes, when the service accepts disposable email domains. TempMailGrab receives the message and highlights detected OTP codes so you can copy them quickly.
How long does the OTP inbox stay active?
The default TempMailGrab web inbox lasts 24 hours, with a one-time extension available. API-created inboxes can use shorter or configured lifetimes within allowed limits.
Should I use temp mail for long-term 2FA?
No. Use temporary email only for short-lived verification. Long-term 2FA, recovery, banking, subscriptions, and accounts you care about need a permanent address you control.
