v0 runs on a Vercel account, so a disposable email has to survive Vercel's own signup flow first — here's exactly how that works.

v0 doesn't have its own separate signup — it runs entirely on a Vercel account, so the real question is whether Vercel accepts a disposable email. It does: Vercel's signup sends a confirmation link to whatever address you provide, and a temp inbox receives it without issue in most cases. Vercel also offers GitHub and GitLab OAuth sign-in, which many developers use anyway since v0's generated projects deploy straight to Vercel under that same account.
How to sign up for v0 with a temporary email

- Open inbox Me and copy your generated disposable address.
- Go to v0.dev and click Sign up — you'll be redirected to Vercel's account creation page.
- Paste your temp address into the email field and submit.
- Switch back to inbox Me. Vercel's confirmation email usually arrives within 30 seconds.
- Click the confirmation link, which redirects you back into v0's chat-to-UI builder, ready to use.
Common verification blockers

Because v0 is layered on top of a full Vercel account, anything that blocks Vercel signup blocks v0 too — this includes occasional disposable-domain filtering and IP-based rate limits on new account creation. If you plan to deploy real projects through v0 rather than just prototype, use a permanent email from the start: Vercel ties billing, custom domains, and team invites to that same account address.

Frequently asked questions
- Do I need a separate v0 account, or does it use my Vercel login?
- v0 uses your Vercel account directly — there is no separate v0-only signup. Whatever email or OAuth method you used for Vercel is what you use to sign into v0.
- Does Vercel accept disposable email addresses?
- Generally yes. Vercel's confirmation-link signup works with most inbox Me addresses. If yours is rejected, try GitHub or GitLab sign-in instead.
- Will I lose my v0 projects if my temp mail inbox expires?
- Your Vercel account and any deployed projects stay intact — the email is only needed for login recovery and notifications. If you plan to keep using the account, switch to a permanent email in Vercel's account settings before the inbox expires.
