Public Bitcoin address vs wallet file: why an address alone cannot restore access

A public address is designed to be shared. Spending requires the corresponding private-key material, which the address does not reveal.

What an address can show

An address may help verify that funds exist, identify a transaction history, or confirm that a recovered wallet corresponds to the expected holdings. It is not a password reset token and is not a backup.

What may restore access

Depending on the wallet, useful material can include an encrypted wallet file, a legitimate seed or mnemonic held privately by the owner, a hardware-wallet backup, a keystore file, an old device, or a password plus partial clues. Different formats require different analysis. Owners with an intact Core file can review the Bitcoin Core wallet.dat password recovery guide; owners with a legacy web-wallet export can review the Blockchain.info wallet.aes.json password recovery guide.

When recovery is not plausible

If only a public address remains and all private-key-bearing material is gone, there is normally nothing to decrypt or reconstruct. This is fundamentally different from forgetting the password to an intact encrypted wallet.

Use the address safely

A public address may be supplied later to verify scope, but ownership must still be established. Never confuse an address balance with proof that a person is authorized to recover it.
