This is a FAQ in regards to an upgrade introduced in CoinWallet / CoinsDo Wallet mobile app version 2.0.25 to change the way how the app to better protect your wallet private key.
How does it work after upgrade?
After the upgrade, your wallet is protected using your device’s built-in secure system module (HSM) instead of app-only protection.
This means sensitive wallet data stays locked within your device’s secure environment and is harder to access even if someone gets hold of your device data.
Will it affect app experience?
Instead of using your app unlock password, your device’s verification will be used for certain actions.
If biometric verification isn’t enabled, you’ll use your device’s passcode to confirm transactions.
2FA (if enabled) and app unlock still apply as usual.
If you’re using a custom derivation path, you may be asked to verify when adding a new address that hasn’t been added before.
Starting from version 2.0.25, all new wallets will automatically use this upgraded security feature.
Do I need to do anything now?
Tap “Upgrade Now” and use your fingerprint, face, or device passcode to verify.
Can I upgrade later?
Yes, but we strongly suggest to do it as soon as possible.
What about Chrome extension version?
