No. Phantom does not support restoring a wallet from an iCloud or Google Drive backup. Those backups can restore the Phantom app, but they do not restore wallet access, and sometimes your wallet may end up in a watch-only state.
To restore access, you’ll need the credentials used to create the wallet:
- Wallets created with a Google or Apple login: Restore the wallet by signing in to the same Google or Apple account and entering your four-digit PIN.
- Wallets created with a Secret Recovery Phrase: Restore the wallet by importing the same 12- or 24-word recovery phrase.
