Back up keys with a passkey
Save your trading keys to a passkey so a new phone or computer can use them without a wallet signature. Prow stores only an encrypted copy.
On this page
Trading keys live on one device. A new phone, a new browser or the installed app starts without them. Normally your wallet then has to sign a new key.
Key backup fixes that. It locks your keys with a passkey. On a new device you unlock them with Face ID, Touch ID or your PIN. No wallet signature.
How it works
- Your keys are encrypted on your device with your passkey.
- Prow stores only the encrypted copy. Prow cannot open it.
- A new device downloads the copy and unlocks it with the same passkey.
- The keys can still only trade. They can never withdraw or transfer funds.
Key backup is off by default. You turn it on.
Turn it on
Open Settings > Security
Find Key backup: "Use your trading keys on other devices. Prow can't open the backup."
Turn on Key backup
Your device asks you to create a passkey. Save it in your password manager.
Done
You see Key backed up or, for several keys, 2 keys backed up.
You can also back up right after you connect a venue. The success screen shows Use this key on your other devices. Tap Save to passkey, or Add to backup if you already have one.
New or renewed keys need your passkey once. Settings shows 1 key on this device isn't backed up until you add it.
Restore on a new device
Sign in to Prow on the new device
Use any of your sign-in methods.
Tap Use passkey
The Turn on trading window lists each account with its venue.
Confirm with Face ID, Touch ID or your PIN
Passkey on your phone and you are on a computer? Choose Use a phone or tablet and scan the QR code.
Not now is fine. The window stays hidden until you open the browser again, or until Portfolio's Turn on trading asks for it. You can restore any time in Settings > Security, where it shows 1 key can be restored here.
Where the passkey lives
Any passkey manager works:
- iCloud Keychain (iPhone, iPad, Mac)
- Google Password Manager (Android, Chrome)
- Windows Hello
- 1Password, Bitwarden, Dashlane
- Hardware security keys
Lost the passkey on this device?
Settings shows Backup passkey not on this device? Create a new passkey there. It replaces your old backup passkey for the keys on this device.
Turn it off
Turn off Key backup in Settings > Security. Every backed-up key is deleted from Prow. Keys already on your devices keep working. A new device will ask your wallet for a signature again.
The passkey stays in your password manager until you remove it. Without backups it unlocks nothing.
Not offered in your browser?
Key backup needs a passkey feature called PRF. Some browsers and passkey managers do not support it. Then Settings shows Not available in this browser, and the success screen does not offer Save to passkey.
Without it, each new device asks your wallet for one signature to approve a key. See How trading keys work.
