I have seen this phone code number thing when purchasing some things like plane tickets.The reason we have passwords is because they work. For an extra layer of security, you can set up what's called 2-auth or second-auth on your email account. That's where you type in your phone number so your email server can text you a code number every time you sign onto your email, or you can choose to select security questions instead, like "the name of my first pet". If your email server offers 2-auth, you'll see those options on the log in page.
Yes, I think you are right. I hope so, anyway.But I don't think it's necessary. Email scammers send you junk email, they don't steal your contacts list or anything. That's done electronically using a phishing tool. Your email address isn't needed by a particular scammer to do that, and most email servers have a security tool that blocks phishing.
My e-post does ask from time to time if I want (or should) update my code.You email page no doubt has a settings icon, and settings has a menu that includes the word security. That's where you can set up 2-auth, if they have it. Check it out if you want. It's a good idea to update your email to ensure you have the most current security tools.
Thank you. I just sent her a message and said "maybe next time".But I'm sure it's safe to give your future e-pal your email address.
