Does the TREZOR Model T and TREZOR One have a password manager?
Yes. Since April 2018, TREZOR One as well as TREZOR Model T support the TREZOR Password Manager. This allows you to manage passwords. The master key is the hardware wallet itself. TREZOR encrypts each password entry separately with a unique key. The signature is derived from a unique private key on the TREZOR. All private keys are generated in its secure offline environment and never leave the device, making TREZOR inaccessible to hackers or malware.
