Monero CLI will then ask you to give your wallet a password and confirm it. Since your wallet will hold your private keys and seed, it is really important to enter a strong password.
Most Monero wallets ask the user to write down a mnemonic seed on a paper backup when a wallet is being created. So it's up to you to remember where and how you stored your mnemonic seed.
Next, Monero CLI will ask for a `Restore height`. Even though it is optional, it's not recommended to leave it blank, since setting a restore height makes your wallet synchronization faster. Ideally it should be the number of the block which included the first incoming transaction to your wallet. Alternatively, you can also enter the date or an estimated date (YYYY-MM-DD format) of the first incoming transaction.
On the next field, type your 25 word `mnemonic seed`. It is expected that some mnemonic seeds have repeated words, as they work as a verification for errors (checksum).
The next field allows you to enter a `Restore height`. Even though this field is optional, it's not recommended to leave it blank, since setting a restore height makes your wallet synchronization faster. Ideally it should be the number of the block which included the first incoming transaction to your wallet:
Therefore, if you're unsure about the block height of your first incoming transaction, it's always better to set a lower restore height instead of a higher one.
The wallet restore height is a setting that tells your wallet software at which block height it should start scanning the blockchain looking for transactions. Ideally it should be the number of the block which included the first incoming transaction to your wallet.
