Password protecting a Proton alias email revealed my actual Proton email address

> Also is it just me or is it strange for a business to not accept encrypted content? How bizzare. Very common in my experience. No encrypted files, no encrypted folders, and if I visit them in person, they won’t accept a flash drive. It’s likely a security policy to prevent malicious attachments and files. Not the dumbest rule considering they lose nothing by allowing my sensitive data to be transmitted without encryption, but they expose themselves to potential security risks by accepting encrypted files and random flash drives. The only people I’ve encountered that accept encrypted files are small business professionals, like my former accountant. And no, they’re not going to install Signal lol. I was truthfully surprised this business was even willing to accept the Proton encrypted password option. Most businesses are either using Microsoft 365/Outlook or Google Workspace. It took a few minutes for me to explain that Gmail’s “confidential mode” (which they recommended) is not the same as an encrypted email and that Google can still read the content.
