As most of you have used Proton Mail as your Primary email address, your using masked emails to protect your primary account with services such as SimpleLogin.
What are you using for your recovery email address for your primary (proton) account?
Considering digital minimalism have you considered email address you do not use? My example is @ vzwpix.com I’m not using it for anything. You might have an apple account, you have to create to set up and apple product.
What threats do you have sharing this email with Proton Mail? What threat do you have receiving an email from Proton mail with this account?
I would be upset with you for hanging on that gmail account but i still hanging on mine. I check in an audit what is still going to that account and maintaining access to stop someone else creating the same account if i deleted it.
Probably not a threat but keeping gmail out of my business.
You could make your Protonmail’s recovery email a family member’s email address, and set a recovery phone for it. So you don’t lose access to Protonmail. Use this email as the recovery email for your other accounts.
I don’t like Tutanota because they don’t allow for a recovery email or recovery phone.
Adding a recovery email address to your ProtonMail account allows you to re-gain access to the account, but doesn’t give you access to emails sent/received before you re-gained access. In addition, it reduces ProtonMail’s security to that of the account used for recovery.
The recovery phrase is a better option as it is used to encrypt a copy of your ProtonMail private keys. So you regain access to the account and emails sent/received before recovery. If you’re using a password manager then the main risk is that a password change goes wrong. The recovery phrase covers that risk without introducing any further risks.
