Yahoo checks not only the password when somebody attempts to log into your account, it also looks at the location and computer where the attempt is made. If it looks suspicious (such a device you have never used before), Yahoo! Mail can require more than just your password, but you must have enabled two-step authentication.
If you have enabled two-step authentication, a second step is necessary to complete login. This can be a code sent to your mobile phone or answering security questions. You can also turn off the latter and require only mobile phone verification.
The Yahoo! Mail account is then as secure as your password and access to your mobile.How to protect your account with two-step authentication.
To add a second layer of authentication for suspicious login attempts (from a new country, for example) to your Yahoo! Mail account:
- Hover the mouse cursor over your name or icon in the top Yahoo! Mail navigation bar
- Select ‘Account Info’ from the menu
- If prompted, type your Yahoo! Mail password under ‘Password’
- Click on ‘Sign In’
- Under ‘Sign-In and Security’, follow the ‘Set up your second sign-in verification’ link
- Under ‘Further Protect Your Account’ make sure ‘Check this box to turn on the second sign-in verification’ is checked
- If you already have a mobile phone number associated with your account, click on ‘Use Current Phone’ to use it for two-step authentication or click on ‘Use New Phone’ to use a different phone number.
Please note that the form on this page may not allow you to enter phone numbers in all the countries Yahoo! can actually deliver verification codes to. You can add those mobile numbers on your account (see below).
If you have not yet set up a mobile phone number or chose ‘Use New Phone’
- Enter your phone number under ‘Second Sign-In Verification Setup: Add Mobile Phone’
- Click ‘Receive SMS’
- Type the verification code received at the number under ‘Enter code’. The code is not case-sensitive
- Click on ‘Verify Code’
- To request SMS message verification under ‘Your second sign-in verification is turned on’, choose ‘Use only my mobile phone number for verification’.
- For a two-step authentication with a password and security question, you can choose ‘Use either my security question or mobile phone number for verification’.
Two-step authentication will only apply when you are accessing through the website, not when you are using an App on your phone or PC.
How to add a mobile number not recognised on the two-step verification form

- Click ‘Add another under Mobile Numbers’
- Enter your mobile phone number
- Click the country code to pick a different one

Hotmail
To enable two-step authentication, visit the https://account.live.com and then navigate to https://account.live.com/proofs/Manage. Here, you will see a link to set up two-step verification.
Please note: You cannot have other Microsoft accounts linked to the Microsoft account you are trying to enable two-step authentication for. If you do, you will be prompted to unlink the accounts.
There is a short wizard. All you really need to do is be contacted via one of the alternate methods you previously supplied, for example a second email address. Microsoft will send a code to that account with the message “We need one more way to make sure you’re you”. When you enter the code, it enables the two-step verification.
Use two-step authentication
Two-step authentication is used in two ways - a security code or an app password. Put simply, whenever you need to sign into anything with your Microsoft account credentials (username and password), try doing so normally. If it works, great. Otherwise, you could be prompted to enter a security code. If not, you will need an app password.
Security code
If you have signed into Windows 8 with a Microsoft account and trusted the PC, you would have seen the security code prompt: ‘Microsoft will send a text message to your mobile phone that contains this code’.
