If this is truly a non-custodial Blockchain.com wallet, the Wallet ID and email are not enough to recover the funds by themselves.
The Wallet ID is mainly an account/login identifier. The BTC public address only lets you view the funds on-chain, not spend them. To move the BTC, you need access to the private key/seed or a recoverable encrypted wallet backup plus the correct password.
What I’d check:
- Old devices where you accessed the wallet
- Browser saved passwords / password managers
- Email archives for old Blockchain.com backup files or wallet-related emails
- Local backups, old hard drives, Time Machine/Windows backups
- Any exported wallet file or encrypted backup you may have saved
- 2FA/authenticator recovery if login is blocked by 2FA
Do not trust anyone DMing you with “recovery services.” If they ask for money upfront, remote access, or private info, it’s almost certainly a scam.
I wouldn’t try to “bypass” anything with cookies. Preserve the old device, don’t wipe it, and if the funds are significant, consider a reputable local data recovery specialist to look for old wallet backups or saved credentials.
Without the seed/private key, password, or wallet backup, there is no technical way to spend the BTC from the public address alone.
