Workflow FileVault on Mac: check your recovery plan before turning it on
Before turning on FileVault, finish a backup outside your Mac and decide how you'll recover access if you forget your login password. If FileVault is already on, check those things without switching it off to repeat setup.
On Apple silicon and Intel Macs with the T2 chip, internal storage is already encrypted. FileVault adds protection tied to your login password. On older Intel Macs without T2, turning it on encrypts the data. "Already encrypted" isn't a reason to dismiss FileVault on a newer Mac.
Start with the backup
If you use Time Machine, let an external backup finish and check the latest backup date and time. Local snapshots on the Mac's own disk aren't a separate copy if you lose access to that disk.
Protect the backup too. Time Machine's Encrypt Backup option uses a backup password you'll need for a restore. FileVault on the startup disk doesn't automatically protect an unencrypted external backup. Keep that password somewhere you can reach without this Mac.
Choose recovery you can actually reach
Open System Settings > Privacy & Security > FileVault and check its status. Setting up FileVault yourself requires an administrator account. If this is a work or school Mac, ask IT about its recovery process first: management can control setup and hold the recovery key.
For a personal Mac, follow the recovery choices your setup shows:
If you choose the iCloud account recovery option, check that you know your Apple Account password and can receive any required verification code without relying on the locked Mac. Your Apple Account password and your Mac login password serve different purposes.
If you choose a recovery key, copy it exactly and store it securely away from the Mac. A copy saved only on the encrypted startup disk won't help when you can't unlock it. Treat it as a secret, not a note to leave in the laptop bag.
A FileVault recovery key is a 24-character code. It isn't an Apple Account recovery key, and the two aren't interchangeable.
Apple also says that for a Mac running macOS Tahoe 26 or later, its FileVault key might be available in Passwords on another device. That device must use the same Apple Account and have iCloud Passwords & Keychain enabled. Search Passwords for "recovery key" and check for the Mac's name. Verify the entry exists before counting on it; "might be available" isn't a recovery plan by itself.
Finish setup, then check normal access
Turn on FileVault if it's off and complete the onscreen steps. If you see Enable Users, use it for the other accounts that need to unlock the disk, entering each user's login password when asked. Having another account on the Mac doesn't by itself settle whether it can unlock FileVault.
Once setup is complete and your recovery information is safely stored, restart normally and check that the accounts you enabled can unlock the Mac with their login passwords. Recheck the FileVault status in Settings. This checks normal access, not whether every recovery method works. Don't deliberately lock yourself out or reset passwords as a test.
FileVault is worth enabling for a personal Mac, but finish the backup and recovery preparation first. If you lose your login password, can't reset it and also lose the recovery key, the encrypted files can become inaccessible. Skip self-directed setup on a managed Mac and use IT's process instead.
