Warframe players, rejoice: Cross-play and cross-save functionality are now in development. … You’ll be able to form a squad with your friends regardless of what platform they’re using, and play the same Warframe account on every platform and continue your journey wherever you’d like.

As far as I know, you can’t. You’ll be able to replicate your PC account to the Switch, but they will go forward independently of one another from there on out.

Yes, even with the PlayStation 4 and PlayStation 5, ‘Warframe’ will have crossplay and cross-save. When the New War expansion launches later this year, Warframe will offer full crossplay and cross-saving across every platform. That’s PC, Xbox One, Switch, and yes, even PS4.

When will Warframe have crossplay? While gamers have awaited this functionality to be implemented within the game, Digital Extremes announced during TennoCon 2021 that crossplay and cross-save would be coming later this year with a future update.
