SteamOS natively supports WireGuard - so you can generate a WireGuard configuration for ProtonVPN on the web and configure it in system settings > network > connections > add new connection.

This is nice but I don’t love that it completely overrides the calendar color. Makes it difficult to tell what event is from what calendar.

My favorites:

• Proton Pass
  • Pros: Aliases, Proton integration
  • Cons: No passkeys (yet), native desktop apps in beta
• 1Password
  • Pros: SHH agent integration!
  • Cons: Least open
• Bitwarden
  • Pros: Most open, self hosting option
  • Cons: least polished user experience

WireGuard also definitely works!
