One of the privacy properties of BIP32 is that given two public keys (or even private keys), you cannot even tell whether they were generated from the same xpub or two distinct xpubs.

Mnemonic generation is a multi-step process. BIP39 is the use of a mnemonic phrase -- a group of easy to remember words -- to serve as a back up to recover your wallet and coins in the event your wallet becomes compromised, lost, or destroyed. The overall HD wallet implementation is a byproduct of several Bitcoin Improvement Proposals (BIP), specifically BIP32 for the core cryptography and key generation, BIP39 for seed phrase and recovery, and BIP44 for multi-protocol account hierarchy. If you were running a prior version as an online wallet without a strong password, you should consider the wallet compromised and create a fresh wallet with version 3. Some are chosen by the user or the wallet software, like the change variable. m / 44' / 12586' / account' / 0 / 0. Advantages: Many functions can be taken out and used individually. Purpose field.

Bitcoin is first crypto currency introduced by an anonymous person or group named 'Satoshi Nakamoto'. The entire point of BIP32 is to allow you to give the private key any given address chain without allowing them to control everything. you need to regenerate the key pair for this address by using the same index you used to derive it in the first place. Using a single seed phrase (stored internally on the device, and also written down external to the device, neither copy should ever be online), you can generate an infinite number of addresses for your wallet.
