How can I force a cognito token refresh from the client

Question

I am using aws amplify and I know that the tokens get automatically refreshed when needed and that that is done behind the scenes.

What I need to do is change a custom attribute on the user in the cognito user pool via a Lambda backend process. This I can do, and it is working. However, the web client user never sees this new custom attribute and I am thinking the only way they can see it is if the token gets refreshed since the value is stored within the JWT token.

Answer 1

The correct solution as of 2021 is to call await Auth.currentAuthenticatedUser({bypassCache: true}).

Answer 2

Here is how you can update tokens on demand (forcefully)

import { Auth } from 'aws-amplify';

try {
  const cognitoUser = await Auth.currentAuthenticatedUser();
  const currentSession = await Auth.currentSession();
  cognitoUser.refreshSession(currentSession.refreshToken, (err, session) => {
    console.log('session', err, session);
    const { idToken, refreshToken, accessToken } = session;
    // do whatever you want to do now :)
  });
} catch (e) {
  console.log('Unable to refresh Token', e);
}
