Where Does Coinbase Wallet Store Keys and Backups?
Coinbase Wallet pairs extension storage with optional encrypted iCloud and Google Drive file backups.
Last updated
Coinbase Wallet stores encrypted keys in the browser extension under ID hnfanknocfeofbddgcijnmhnfnkdnaad, and optionally backs the phrase to your own iCloud or Google Drive with AES-256-GCM. Coinbase holds neither the phrase nor the backup password; both live strictly with you.
The cloud copy trades paper for passwords. It rescues a lost phone with account plus password, but a forgotten password bricks it as thoroughly as a lost phrase. Keep the manual phrase backup anyway; Coinbase recommends both, and so does everyone who has ever needed the second one.
Where Coinbase Wallet stores this, by platform
%LOCALAPPDATA%\Google\Chrome\User Data\Default\Local Extension Settings\hnfanknocfeofbddgcijnmhnfnkdnaad
Extension vault under the Coinbase store ID. Cloud backups are per-wallet and password-gated. Keep the written phrase regardless; cloud plus paper beats either alone.
~/Library/Application Support/Google/Chrome/Default/Local Extension Settings/hnfanknocfeofbddgcijnmhnfnkdnaad
Same extension-ID folder on macOS. iCloud backups restore with the same cloud account plus the backup password you set.
~/.config/google-chrome/Default/Local Extension Settings/hnfanknocfeofbddgcijnmhnfnkdnaad
Same extension-ID folder under the Chrome config root. Android leans on the Google Drive encrypted backup instead of files.
Frequently asked questions
How do I restore Coinbase Wallet from a cloud backup?
Reinstall, choose existing wallet, and enter the password backing the cloud copy. Same cloud account plus correct password restores the phrase. Lose the password and the backup is unreadable forever.
Do multiple Coinbase wallets share one backup?
Yes, one wallet per backup. Each recovery-phrase wallet carries its own phrase and needs its own cloud backup entry. Back them up separately and label the passwords.
