Even if you choose to stay signed in when you log in to Yahoo, Yahoo still might prompt you to log in each time you check your Yahoo Mail. If this is the case, then the browser isn't saving login cookies, which are bits of data that let Yahoo know you're a return visitor. To stay logged in to your Yahoo Mail account, make some adjustments to the browser security settings.

Information in this article applies broadly to using Yahoo Mail on any device with any browser.

When You Have to Log In to Yahoo Mail

The cookie a browser saves when you visit Yahoo Mail applies only to the browser and device you were using at the time of your visit. As long as you visit the login page with the same device and browser, you shouldn't have to log back in. However, if you log in with a different device or browser, Yahoo won't find the login cookie, so you'll have to enter your username and password.

If you are using the same device and browser, but you are prompted to log in, the cookie in the browser that logs in to Yahoo mail automatically was deleted.

How to Stay Logged In to Yahoo Mail

You can prevent your computer from deleting browser cookies, including the one for your Yahoo Mail login credentials, in a few ways.

Don't Delete Cookies

Do not clear browser cookies manually. Also, check the browser settings to make sure it isn't set to delete cookies when the browser window closes. If you run browser extensions and anti-spyware that automatically clears the browser history, disable them or make an exception for the yahoo.com domain.

Don't Use Private Browsing

For enhanced internet privacy, use the browser's private browsing feature to visit websites without storing cookies on your computer. That way, the browser doesn't track your internet history, but you'll have to sign in to Yahoo Mail each time you visit. Using this feature frequently may explain why your login information isn't saved.

The various browsers have different names for the private browsing feature:

If you prefer not to log in to Yahoo Mail each time you visit, don't use private browsing.
