I received an email from Bitwarden inviting me to update my credit card for renewal. The link took me to a Stripe URL instead of a Bitwarden URL so I have no way of knowing if this was phishing or an email from Bitwarden.
Apparently this was legitimate, but this invites phishing as Bitwarden users come to expect Bitwarden emails to link to Stripe. Anyone with a Stripe account could use this to phish Birwarden users.
Updating subscription information while logged into Bitwarden has been disabled so Update Your Billing Information | Bitwarden Help Center this no longer works.
Any engagement users have with Bitwarden should be available within the Bitwarden.com domain.
