How do you work with mail (on different devices and computers)?

Question

Google

Greetings.

I think most habr users have mail on Google and have a mobile device that also uses mail. It is interesting who and how solves the issue of security, especially in cases of loss of a mobile device.

For example, I now have the following structure (everything is considered in the context of google and its mail):

There is a main mailbox with a beautiful name, with a very complex password, let's call this mailbox A . Forwarding all letters is set from this mailbox to another mailbox in which work with letters is already underway (of course, it is configured there so that the answer comes on behalf of mailbox A), let's call this box B.
On the phone, there is a third box, which also receives letters from box A and is configured to send letters on its behalf, let's call this box B.

As a result, we get that our main box A is maximally protected, because. we don’t go to it and don’t enter passwords anywhere, but we use box B on his behalf. It’s also not very scary if we lose the phone, because. box B is registered there and nothing will happen to box A.
These are all pluses, but there are also tangible minuses:

1. despite the fact that mailbox B is configured to respond on behalf of mailbox A and its SMTP, some mail systems still substitute mailbox B or C as the sender's mailbox
2. using all sorts of Hangouts becomes hell, because. you have to add new contacts on each box and explain to people why this is done
3. people, seeing your main mailbox, try to share the Google document for this mailbox (A) and it is impossible to enter it from mailbox B

and the further, the more these disadvantages become more significant.

How do you solve such problems?

Answer 1

Never done something like this. The main mail is on gmail, all letters go to it (and from other mailboxes like hotmail.com, mail.ru) and are sent from it. One question - why do you need a separate mail ( B ) on your phone? Is it possible to work with B ?

Answer 2

And what for? I don’t even have a password on my phone, because it’s idiotic to enter a password 150 times a day for the sake of a situation that most likely will never happen, and if it does, there will be nothing terrible. For if the phone is stolen, they will immediately clean it. And in any case, I can always change the password and the mail will not be lost.

Answer 3

At first, I also tried to set it up in this way, but quickly realized that it was inconvenient and began to use one account everywhere.

Answer 4

In the mail, the mail itself is valuable, and not the login-password to the mailbox.
Turn on two-factor authentication, fill in your Google profile information, set a complex password. Then even if you lose access to your account (lost your phone, for example), you can easily return it through Google technical support. And the confidentiality of your correspondence can not be returned.

Answer 6

Two-factor authentication in mail based on SMS + two-factor authorization in lastpass based on google authenticator = quite enough.
