When you create an email, and you want to send to a non-proton user, if you click the lock icon, you have to set a specific password for that email. Then it will be password protected/encrypted, and only openable with that password. NOT your account password. You shall not share that with anyone!
Yay! Thanks for clarifying. I was not too keen on sending my main password to my ProtonMail account out.
No problem. I am glad we discussed this before you shared it. 💜 Rule 1: Never share your password with anyone! If you have to. They try to scam you, or you need to use a different product 🤙
