No need. Even selfhost is free. The catch all feature is also included in the free plan. Bitwarden free is amazingly packed with pretty much all the features you need. Tip: Make a ‘non-profit’ organisation and invite your family to it. You can share passwords for streaming service etc using this.
Got a domain? Setup ‘catch all’ and you are all set. If not consider a cheap one. It’s unlimited disposable email addresses for few buck a year.
Catch all? I love it so damn much since I got it. Bitwarden added it on the fly and now I got disposable email addresses for anything I can think of, it’s so, so perfect!
