Peanut uses passkeys, which are stored in your device’s own system:

• Apple devices: iCloud Keychain
• Android/Chrome devices: Google Password Manager

To log in on another device:

• Make sure you’re signed into the same Apple ID or same Google account
• Make sure passkey syncing is turned on

Your passkey will then appear automatically on your other device.

🧩 If your devices are from different ecosystems

Example: you created your account on a Mac (Apple) but want to log in on Android.

Passkeys don’t transfer between Apple and Google.

👉 In this case, the best option is to create a new account on the device you’ll use the most.
