Passkeys on Seldeo
Passkeys are the only way to sign in to Seldeo, so managing them well is the closest thing the account has to key hygiene. This article covers the management screen itself. For how sign-in works day to day, see Signing in to Seldeo; for the technology, the guide Passkeys explained is the deep dive.
Where your passkeys live in the app
Go to Settings → Account → Account security and tap Passkey. The Your passkeys screen lists every passkey that can currently sign in to your account.
Each entry shows the authenticator it belongs to and one of two labels:
- synced — the passkey is stored in a platform credential manager (iCloud Keychain, Google Password Manager) and follows you to other devices signed in to the same platform account.
- this device only — the passkey is bound to this hardware and exists nowhere else. If the device goes, so does the passkey.
That distinction is worth checking once: if every passkey on your list says this device only and they all live on one phone, that phone is a single point of failure.
Add a passkey
On the Your passkeys screen, tap Add a passkey and approve your device's prompt. Do this on every device you use Seldeo from.
The screen's own guidance is the policy we recommend: add one on each device you use, and keep at least two so you're never locked out.
Rename a passkey
Passkey names default to the authenticator that created them, which gets ambiguous once you have a few. Tap Rename on an entry, give it a name you'll recognize ("Personal phone", "iPad", "Work laptop"), and tap Save.
Renaming is cosmetic — it changes the label, not the key.
Remove a passkey
Tap Remove on the entry, and confirm on the Remove this passkey? dialog. From that moment the removed passkey can no longer sign in to your account.
Two safety properties to know:
- Removing is a step-up action. You confirm with another passkey, so a person who briefly picks up your unlocked phone can't quietly strip your account's keys.
- You cannot remove your last passkey. The app refuses with "Add another passkey before removing your last one." An account with zero passkeys would have no way to sign in at all.
Remove a passkey whenever the device that held it is sold, recycled, or permanently retired. If the device was lost or stolen rather than retired, do the same — and read Recovering a lost account if the lost device was your only one.
If you're down to one passkey
Treat it like the last copy of a house key:
- Add a second passkey now, on a different device if you have one.
- Confirm your recovery codes are still somewhere you can reach — they are the fallback if the last passkey disappears.
