Antwort auf: Auf Trezor habe ich meinen Pin, meine Seed Phrase und meine Passphrase … aber was ist mein privater Schlüssel?
When using Trezor, the private and public keys are _implementation details_. Asking about them is sort of like asking how a CPU relates to Reddit: there _are_ CPUs involved, but you are several layers removed from them.
Your seed is _not_ a private key (both the other answers are wrong), but it is kind of the closest thing. A much better term is a **secret**. Trezor can regenerate all your actual private keys (and there are in fact lots of them under the hood) from this secret plus a passphrase.
Your _addresses_ are the closest thing to public keys. Each address is a thing that you can safely reveal if you so choose. Behind the scenes, Trezor keeps them associated with keys.
(To be precise: every address is described by a _derivation path_. Combine your seed, passphrase (if any) and the derivation path and you get a public/private key pair. You can use the public key to derive the address that you give out. And you can use the private key to sign transactions for that address.)

Using different words:
* your **seed** is the main secret
* your **PIN** is to seed as a password is to a password-protected pdf. You need it to decrypt the seed to start working with it.
* your **passphrase** is an additional secret
Just like the vaults in heist movies, you need two people to turn two „keys“ at the same time. One of the „keys“ is the passphrase, and it’s always carried by the boss on their person. (This is a thing you keep only in your memory.) The other „key“ is stored in the CEO’s personal safebox (encrypted), and you need to know the combination (PIN) to get it out.
The private/public keys are _contents of the vault_.
