When you want to make a transaction you can plug in your Trezor and it will provide the keys to sign off on a transaction, which is done by physically pushing buttons on the device.
Its design protects your cryptocurrency by ensuring keys are always offline and by requiring physical interaction to confirm a transaction and prevent remote theft.

If you want a hardware wallet with more security against physical attacks, you may want to compare other options.
Despite the risk of physical attack, Trezor still offers a high level of security by virtue of being a hardware wallet.
- Hardware wallet: These types of wallets ensure your funds are held offline.
- PIN protected: To access the device you need to enter a PIN.
- Back-up phrase: In the event of loss or theft of your device, you can use the seed phrase to restore your wallet on a new device.
- Open source: Trezor’s design and firmware is open-source and has been heavily scrutinised.
There has only been one confirmed vulnerability of the Trezor One, which involved using an oscilloscope to read energy spikes on the device when plugged in, and from there to decipher the private keys. This issue was fixed years ago, before it was publicly disclosed.
