What to expect
Facebook accounts are checkpointed aggressively, and every checkpoint is resolved by email or phone. Without a reachable inbox, a checkpoint is the end of the account. There is also a real-identity policy to consider, so a throwaway address does not fit the platform's own rules.
If you decide to try it
- Open the temporary email generator and copy the address that is already waiting.
- Paste it into the signup form for Facebook.
- Watch the inbox — messages appear on their own within seconds of delivery.
- If nothing arrives within two or three minutes, the address was almost certainly filtered. See why websites block temporary email.
The honest caveat
Whatever the verdict above, a disposable inbox expires. If you would be upset to lose the account, register it with an address that will still exist next month. The comparison in temporary email vs email aliases covers the alternative.
