Looking to onboard your credentials to Muse? Unfortunately, there is no way to bulk import credentials from iCloud Keychain or 1Password into Muse (that's by design), but you can semi-automate the process pretty quickly. Full details in the tweet below.
Just tell Muse what service you need in chat and it'll pop a secure entry card, tap it, paste the key, done. The secret goes straight to the vault and never touches chat.
No Mac required. The cards render right in the Muse iPhone/iPad app, OAuth connects just open the provider's sign-in page, and iCloud Keychain or 1Password autofill works inside the secure form (I do it via 1Password). iOS suggests the matching login when you tap the field, one tap fills it. Seconds per credential.
Unfortunately, OS won't let any app bulk-import from Keychain (Apple only exposes it via AutoFill), and there's no zero-touch setup. Closest thing to bulk is giving Muse your list of sites so it can queue a secure card per site, and you tap through them rapid-fire with AutoFill filling each one.
Each card still needs your tap, the sign-in, the consent, and the vault approval. Apple likes the Human in the Loop, apparently. I was able to go through about 30 credentials from 1-password in about 10 minutes. Hope this helps!
