Why Yahoo Mail Doesn't Keep You Logged In

Learn how to stay signed in to Yahoo Mail on any device

Even if Stay signed in is checked on the login screen by default, Yahoo still might prompt you to log in each time you want to check your Yahoo Mail. If this is the case, then your browser isn't saving login cookies, which are bits of data that let Yahoo know you're a return visitor. You can stay logged in to your Yahoo Mail account by making some adjustment to your browser's 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 your 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 attempt to 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 still prompted to log in, then something or someone deleted the cookie in your browser that would log you in automatically.

Don't Delete Cookies

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

Don't Use Private Browsing

For enhanced internet privacy, you can use your browser's private browsing feature to visit websites without storing cookies on your computer. That way, your browser won'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:
