Your Mailspring ID is missing required fields

I’m getting an error message, “Your Mailspring ID is missing required fields.” How do I fix this?

This error message appears when Mailspring was unable to save your Mailspring ID password to your system keychain or keyring.

Linux

Make sure you’ve installed libsecret through your package manager. Then quit Mailspring, reset its settings by deleting $XDG_CONFIG_HOME/Mailspring or ~/.config/Mailspring. Then re-launch the application.

macOS

Quit Mailspring and delete its data in ~/Library/Application Support/Mailspring. This folder may be hidden on your system - the easiest way to delete it is to open Terminal.app and type:

rm -rf "~/Library/Application Support/Mailspring"

Then, re-launch Mailspring and sign in to your Mailspring ID again.

Windows

Quit Mailspring and delete its data in C:\Users\<You>\AppData\Roaming\Mailspring. Then, re-launch Mailspring and sign in to your Mailspring ID again.
