TonKeeper signing represents a way to sign transactions on the TON blockchain using the TonKeeper wallet app. It is a method to ensure that the sender of the transaction is the owner of the wallet address by requiring a valid signature from the wallet. The TonKeeper app generates a private key that is securely stored on the device and is used to sign transactions.

"Signing Log-in" is a way to log in to the TonKeeper app without entering a password. It uses the biometric authentication feature of the device to verify the user's identity and log them in.

**The structure of wallet signing in TVM is generally considered safer than in EVM because it is done on the browser level and the private key is stored securely on the user's device, rather than on a third-party server. **

However, it is still important to take appropriate security measures, such as using strong passwords and keeping devices secure, to prevent unauthorized access to wallets and potential loss of funds.
