Is appleid_gben@email.apple.com a legit email?

I believe "appleid_gben@email.apple.com" is legit.

I wasn't sure, because i had been asked to change my Apple ID password while changing from dropbox to iCloud in 1password.

So i checked the supportwebsite from 1password en found this in step 3

Sign in using your Apple ID if this page on Apple.com opens in your browser. (This won't happen if you are using the version of 1Password from the Mac App Store.)

See:

https://support.1password.com/guides/mac/sync-icloud.html

That's the way i got mails from "appleid_gben@email.apple.com" after changing my Apple ID, since i am NOT using the 1Password version from the Mac App Store.

These are phishing scams. Do not click on any of the links nor call any telephone numbers.

It certainly sounds like someone may be trying to reset the password on your account, in an attempt to gain access.

If you have not done so yet, you would be well-advised to enable two-factor authentication on your Apple ID. See the following page:

Frequently asked questions about two-step verification for Apple ID - Apple Support

(Unfortunately, the formatting on that page is currently screwed up, so it'll be a pain to read, but the information is there.)

In addition, if you enabled Find My iPhone/iPad on those devices, you should be sure to lock them both, if you haven't done so already.

If someone stole your device and you had enabled Find My Phone, then they cannot access your device or account unless the know your Apple ID and password. They may be trying to scam you out of that information.
