What you’re being given
- Backup codes (also called recovery codes): usually 8 to 16 short codes. Each one signs you in once if you lose your phone or authenticator app.
- A recovery key: one long key that gets you back into an account, such as an Apple Account recovery key or a password manager’s emergency kit.
Either one can get someone into your account, so treat it like a password. And you’ll need it on the day you’ve lost the device that normally signs you in, so don’t keep the only copy on that device.
Good places, and what to avoid
- Printed and put away. Simple, and nothing online can reach it. Good for the few accounts you can’t lose: your email, your Apple Account, your password manager.
- An encrypted app on a computer you use, so the codes are there when your phone isn’t.
- Avoid: a screenshot in your photo library, a note that syncs everywhere, an email to yourself, or a text file in Downloads called
backup-codes.txt.
Whatever you choose, write down which account the codes belong to and the date you made them. Old codes stop working when you make a new set.
How Slinky does it
Slinky has a place called Recovery, just for these:
- Paste the whole list. Slinky recognises a set of backup codes and saves them as one item for that account.
- Codes cross themselves off. Copying a code marks it used, since each code works once. When only a few are left, Slinky says so: “Only 3 codes left. Consider generating new ones.”
- Recovery keys get a reminder to keep a printed copy, until you print one or mark that you have it somewhere else.
- Encrypted, with a backup you hold. Everything is in one encrypted file on your Mac, opened with Touch ID. Your own Slinky Recovery Key (print it, or keep it in Apple Passwords) opens it on a new Mac.
- Quick Access (⌥⌘K) finds a code from any app when a website asks for one. Copies are kept out of clipboard history and cleared after 60 seconds.
