You may be asked for your password. On Macs with Apple silicon or the T2 chip, data is already encrypted. Turning FileVault on additionally ties that encryption to your password.
Choose a recovery method
You can allow your iCloud account to unlock the disk, or create a recovery key and not use iCloud. A recovery key is a long code of letters and numbers. Write it down and store it away from the Mac.
Click Continue
Encryption happens in the background while you work. On newer Macs it is almost immediate.
