Geth wallet password recovery requires an intact encrypted keystore and a feasible password search, or another valid copy of the account’s private key. A public address or blockchain history cannot replace missing private-key material.
Preserve the keystore and data directory
Copy the complete original keystore directory and retain all dated backups. The location depends on the operating system and any custom data-directory setting. Use the original node configuration and the official Geth documentation to identify it; do not assume macOS and Linux use the same default path.
Existing JSON keystore versus private-key import
geth account import imports a private-key file; it is not a general command for decrypting or importing an existing encrypted JSON keystore. Restore a compatible keystore through the documented keystore/data-directory process, on copies, and confirm that the expected address is listed. Do not change encryption fields merely to make the file appear to load.
Use the actual cipher and KDF
Ethereum V3 keystores include their cipher, salt, KDF parameters and integrity MAC. Common files use AES-128-CTR with scrypt or PBKDF2. Select a recovery tool that explicitly supports that combination. A tool mode for one KDF must not be advertised as covering every Ethereum JSON file.
Password search and corruption
Useful password context can support a targeted offline search. Its feasibility depends on the candidate space and key-derivation cost; no fixed recovery time applies to every case. Keep private keys and candidate passwords out of public tools and ordinary email.
If a file is damaged, compare intact backups first. Repairing JSON punctuation is different from reconstructing missing cryptographic bytes. The address and ciphertext cannot in general reveal lost encrypted content or its password.
After access is restored
Verify the account address and transaction history before any migration. Ethereum mainnet uses proof of stake; mining instructions are obsolete. Running a current node requires the appropriate execution and consensus clients, and a single execution-client synchronization flag does not establish that every component is ready. Node operation is separate from offline keystore recovery.

Need help with recovery?
Email mail@keychainx.io with the wallet type, approximate date, backup extensions and error message. Describe the problem first; do not send passwords, wallet words, private keys or wallet files in an initial message. KeychainX can assess a wallet you own or are legally authorized to recover. Recovery is not guaranteed.
