How do you store Membership Anywhere digital cards securely?

Hi everyone, Lately I’ve noticed that many museums, cultural institutions, and organizations are moving toward digital membership cards instead of physical ones. Some platforms, like Membership Anywhere, provide digital passes that members can access from their phone or add to mobile wallets. While these solutions are convenient, I sometimes wonder about keeping a secure backup of important membership details. For example, if a membership includes a number, QR code, or digital pass, losing access to the original email or app could make it harder to retrieve later. I know wallet apps like Apple Wallet or Google Wallet can store some passes, but not every organization supports those formats. So I’m curious how others handle this. Do you store things like digital membership cards or membership details inside your password manager, or do you rely entirely on the original app or email?
