Temp Gmail domain accounts. Just Gmail domain address. User has to fill own passwords key for using multiple devices application.

Logged-in Session (No password needed):

If you're signed in on a device/browser and don't log out, Gmail usually keeps the session active for up to 30 days.

After that, it might ask for the password again for security.

2. Inactivity:

If you don’t use the account at all, Google may consider it inactive after 2 years and can delete it.

But temporary or suspicious accounts (like those made without recovery info or used for spam) can be suspended or deleted much faster—sometimes within days.

3. Without recovery options:

If the password is lost and you don’t have a recovery email or phone number, you’ll likely lose access quickly if Google asks for re-authentication.

Temporary Gmail services (often called temp mail or disposable Gmail) work a bit differently from regular Gmail accounts. Here’s how they usually work:

1. No Password Needed

Yes, you don’t need a password to use most temp Gmail services. You just pick a temporary email address or they give you one, and you can view incoming emails right on their site. There’s no login like with real Gmail.

2. How Long Do They Work?

Most temp emails are active for 10 minutes to 24 hours, depending on the service. Some let you extend the time. After that, the address is deleted and any received emails are gone forever.

3. Not Official Gmail

These aren’t actual Google (Gmail) accounts. They’re just using Gmail-style addresses or fake Gmail domains for convenience.
