This is something you set at the beginning before creating a new crypto wallet.
Password is set after you have created the wallet.
You can set in the beginning too, just like normal passwords.
All the wallets that I have used before all requested to set password and not pin. But pin and password are similar and it would be set after the wallet has been created also, just like the password.
3. SEEDPHRASE
This consists 12-24 words or even more.
They are automatically generated by your wallet app.
Similar to Private key.
The seed phrase is not longer than 24 words if you need a compatible wallet for it.
Seed phrase is not similar to private key. Seed phrase generates the private keys, public keys and addresses. The private keys can generate the public keys and addresses but it can not generate the seed phrase. Seed phrase is important because it can generate the private keys.
This is a feature included in today's hardware wallets.
Web, mobile and desktop wallets can support passphrase.
This also unlocks hidden wallet addresses.
No. It generates different keys and addresses which makes your seed phrase to be more secure against offline attack.
I believe this passphrase is best for pro crypto users that are not new to crypto wallets because it can be too complex for beginners, passphrase is case sensitive (Upper case, Lower Case)
There is nothing hard about it. Just know that everything you type counts. Even space is part of characters in passphrase. Yes passphrase is case sensitive.
So that's it, PIN and Password will only stop your friends or family members from unlocking your crypto wallet behind your back, just like how your PIN and Password stops anyone from unlocking your smartphone, and that's it.
Yes, on the device. But if the seed phrase is known, pin or password are both useless because only the seed phrase is needed to steal the coins. But if the seed phrase is extended with passphrase, it would be helpful if you used it while setting up the wallet as it will generate different keys and addresses.
On the other hand, Seedphrase is not to be taken lightly, it is your ultimate key protecting those juicy crypto assets of yours, keep em save, offline and in a open source cold wallet.
Also same to passphrase. If passphrase is used, it is just like the seed phrase if lost because you will not be able to recover your keys and addresses. Which means you will not be able to recover your coins.
