If you are using Javascript SDK you can use getIdTokenResult method and check for issuedAtTime . It is defined as "The ID token issued at time formatted as a UTC string." in the documentation .

const user = firebase.auth().currentUser

if (user) {
  user.getIdTokenResult().then((result) => {
    const {issuedAtTime, expirationTime} = result 
    console.log(`This token was issued at: ${issuedAtTime}`)
    console.log(`This token will expire at: ${expirationTime}`)
  })
}
