What is meany by session validity? | FAQ - Zoho Accounts

What is the session validity for my Zoho account?

By default, if you sign in to your Zoho account, you can access your account without signing in again for the next 30 days, even if you quit the browser. We won't ask you to sign in to your Zoho account unless you manually sign out.
Based on your SAML IDP's policy or organization policy, the validity time might be less than 30 days.

You can refer to our troubleshooting article if you are asked to sign in every time you quit your browser.
