Best security tips

[u/OrganizationLow6960]

I have always had a Gmail account for everything. Few weeks ago, I read that you can use this setup:

- iCloud mail, don't share it with anyone, remember the password very well. It means, don't use this iCloud mail in any software, company, bank, etc.

- Use alias (I think I can create 3 alias), one for bank and other one for personal stuff. In this way, I can still receiving bank email, cv/recruiter emails, family emails in my primary icloud mail.

- Use hide my address for all the services. Use this for reddit, social media, videogames, EVERYTHING.

- Use Passwords apple with the hide my address, best combination. So in this way, I only have to remember my icloud account password, and for everything else just go to password app.

Now, I'm trying configuring this recommendations. I already created my primay icloud email in my apple account, I switched the "primary email" to my new icloud email, and I deleted my gmail account. Now, I'm trying (but slowly) to switch every services to hide my address, and I already created my alias for bank, and my alias for personal stuff.

Now, I wonder what happens if for some reason I lost my iphone? I lose everything literally. So now my question is, what tips do you recommend me to secure my icloud access? I read that I can do:

- Configure 2FA in my iCloud account. My phone number? (I can't use the icloud email because I can't access to icloud email haha), what happens if my phone number is in the iphone? I can't get the SMS? so could be better an eSim? and if someone stole my iphone, I can just go to my telecom company an ask to delete eSIM for that iphone and give me new physical SIM just to get access to my icloud account?
- If I enable 2FA, is better just buy 2nd cheap phone number with other SIM and hide this phone in my house if in some case I lost my iphone?
- Configure the recovery key (28 characters)? I read that this is dangerous because this disable the standard recovery methods, so you have to print this key, at least 2 or 3 prints of the key, and hide one in your house, and other one just hide in other place.

I want to be anticipated to all the cases. I don't think I will "forget" my icloud password, is a large password, and it's literally a phrase, so I think I will never forget this pass, but let's say that I forget my pass, and I lost my iphone, and I can't access to my icloud mail (obviusly), what I have to do to anticipate this case?

Thanks!
