Hello! At present, there are many secure emails, but there are some differences between them. I have used almost all the mailboxes used in China and hotmail(msn) and Gmail used abroad, and I have also used several paid mailboxes. Let me introduce each email first, and then make a comparison.

1. 126 and 163 are all products of Netease. 126 and 163 use SSL 128 bit encryption technology to log in, which can ensure the security of email passwords to the maximum extent. You can absolutely guarantee that the password you enter will not be intercepted by a third-party eavesdropping tool (but if it is, it is the same for any email). Netease's free mailbox is absolutely ahead in function and password protection is also very good. Once the password is stolen, you can get back the email in many ways. For 163, you can use security code and password protection and confidential email. For 126, you can use password protection, confidential email and mobile phone to modify the password. So you should choose a long-term free mailbox.

22 1cn。 This is a mailbox in Guangdong, and the slogan is 10GB capacity. Actually, this is really useless. We can't have so many letters, and the capacity of 2GB is enough to meet the needs for a lifetime. We can calculate that the space occupied by 500,000 Chinese characters is1m. And 1GB= 1024M. In other words, we can write 50 *1024 = 512 million Chinese characters, that is, 565,438+200 million Chinese characters, and 2GB can exceed 1000 billion Chinese characters. We can't use up so many words. And that so-called ... Because the operator knows that the user is not using all the capacity. Besides, I don't feel very good about the quality of email. When I enter the page, there are always advertisements. I am disgusted and have few functions. And there are a lot of the most annoying spam, many of which are advertisements for watching movies sent by 2 1CN company itself.

3. Yahoo email. There are two login methods for this email. Standard mode (not SSL algorithm, but also encryption) is adopted by default. If "Safe Mode" is selected in "Login Mode", SSL encryption is adopted. This email is 3.5GB, and the layout inside is very good. The most prominent feature of this kind of mail is that it has a double postal address, which can cover up the real address and make spam impossible.

4. Sina This mailbox is also 2GB, and spam is rolling in. This mailbox does not use SSL encryption technology, and the functions inside are basic functions. Once someone maliciously enters the mailbox, they can completely tamper with the password-protected questions and answers, so that users can't retrieve the mailbox.

Tom, this mailbox has great restrictions on mail, that is, the total number of letters in the mailbox cannot exceed 1000, which is not commensurate with its capacity of 1.5G. It seems that1.5g is fictitious.

6.hotmail is a product of Microsoft, and I use it to send free emails. Email login adopts SSL encryption technology. This can also be used as a chat tool similar to QQ, which is what we call MSN. The password protection of this mailbox can be modified at will, just know that the password is the same as Sina's.

7.Gmail, this email appears in a very high profile, attracting users through invitations. But now it has been publicly registered, and the function is very good, but the login is very slow, which may be related to the server.

Among these mailboxes, I recommend 126.438+063. Hotmail, Yahoo! . Gmail。

Reason: SSL encryption technology is used to ensure password security. The functions of 126 and 163 are very user-friendly, and hotmail and Gmail tend to be used for business. That Yahoo! In between.

If you want to have a long-term email address, please select 126 and 163, because the password protection question cannot be changed casually, and you must answer the previous answer before changing it.

Actually, I can say the password.

The password is the lock of the mailbox, so you must not be careless when setting it. The password of the email address must be very complicated, preferably numbers+characters+uppercase and lowercase letters, which is not convenient to remember, but it is a great improvement for security. I have read & gt the time to crack the password, 6-digit password is almost instantaneous, 8-digit password is 23 hours, 8-digit+letter is one week, and 8-digit+letter is 23 years. Think about how long it will take if it is a 16 digit password (numbers+letters+characters).

Don't believe what is said on the Internet that you can crack the password quickly. If you can do this, all the mailboxes in the world will be finished. It's impossible to know only the email address.

So the password must be complicated.

There is not only a password, but also a back door like a mailbox-a password-protected question and answer. Yes, that's it. If password-protected questions and answers are easy to guess, it is a failure, especially for people you are familiar with, which is possible. For acquaintances, you must not be careless There is a saying, "Don't hurt others, don't guard against others."

Question: What is the capital of the United States?

Answer: Netease 163 email address

Hehe, that's good. No one can answer. It's not convenient to remember, but it's worth it for safety.

That's my answer. In fact, after choosing a safe mailbox, you should use it safely to keep it safe, right?

thank you
