I'm using the MSAL Browser library Login on js client with using acquireTokenSilent or acquireTokenPopup to get access token and refresh token.

The refresh token I'm getting is valid for 1 day as can be seeing on refresh the access token section: enter image description here

I want to change my login process to get a refresh token that will be valid for 90 days. How is it possible?

My server is .NET Core.

Thanks!

If you need to retain a refresh token for longer, you'll need to use the Authorization Code grant and store it server-side. The expiration of refresh tokens generated using the Implicit grant is fixed at 24 hours.
