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.
