Ok （1）you can use sign in mode ( Need to enable escrow ）and set firebase rules:
`{ "rules": { ".read": "auth.uid != null", ".write": "auth.uid != null" } }`
use UID

(2) key cannot use “@” or “.”
replace “@” to &1 and “.” to &2
Email cannot use & - % #
Key cannot use @ .

Use the Sign-In component to validate Email. The sign-in component will generate a unique ID for each email. Use this UID in your RTDB.
