I'm a relatively new dev working on the sign up feature for a production app and am trying to move the user setup (authentication, user data to database) into a server action. I created a server action that takes in the form data and uses it to create a user auth account and add user data to the DB using the Firebase Admin SDK.

Since the password (as a string) is part of the form data, should I be hashing it before sending it to the server action?

On the client form upon hitting submit button:

await SetUpUser(userData) // Server action to create user auth and data in database
await signIn(userData.email, userData.password) // Sign in client

On the server action:

const userRecord = await auth.createUser({
            email:userData.email,
            password:userData.password,
        })
const userRef = firestore.collection('users').doc(userRecord.uid)

        await userRef.set({
            firstname: userData.firstname,
            lastname: userData.lastname,
            company: userData.company,
            email: userData.email,
            created: Firestore.FieldValue.serverTimestamp(),
            })
