Google's app platform with auth, databases and hosting. Developer platforms verify the address so they can send build, deploy and security notices to a real owner.
Before you use a temporary address for Firebase. If an account will own repositories, domains, billing or production keys, register it with an address you will still control in a year.
When you register, Firebase usually sends a verification link to the address you gave it. The sender, subject and exact wording are Firebase's own and can change, so look for a message that arrived right after you submitted the form.
Firebase email-link sign-in sends a one-time link that works once and expires.
CI jobs and coding agents sign up for sandboxes, trial tiers and test orgs constantly; reading the confirmation mail by tool call keeps the run unattended.
With the Emailsify MCP server, an agent creates an address, fills in the Firebase form, then waits for the verification email. That wait returns only the extracted link, not the whole email, which keeps untrusted text away from the model. See how to connect your agent.
Use a temporary inbox when you only need to look around Firebase and you can afford to lose the account. Switch to an address you own if the account will hold anything you care about, if you need billing receipts, or if you may need a password reset.
Emailsify is an independent service and is not affiliated with Firebase. Follow Firebase's terms of service.
That is Firebase's decision and it changes over time, so we cannot promise it. If Firebase rejects the address, do not try to disguise it. Use an address you control instead, especially for an account you want to keep.
Usually a few seconds after Firebase sends it. The delay is mostly on the sender's side. Keep the inbox open: it refreshes automatically, and Firebase codes and links are short-lived.
No. Mail is deleted 2 hours after it arrives and the address cannot be reclaimed, so a password reset later would go nowhere. Use a permanent address for any Firebase account you intend to keep.
Yes, on a Pro plan. The agent creates an inbox, submits the form, then waits for the link, which it receives the moment it arrives. Whether automating a Firebase sign-up is allowed depends on Firebase's terms.
