"Invalid Token" when trying to authenticate phone number using firebase

Question

This is my code:

import FirebaseAuth


class AuthPhoneNum {

    static func getPhoneNum(phoneNumber: String) {
        PhoneAuthProvider.provider().verifyPhoneNumber(phoneNumber) { (verificationID, error) in
            if let error = error {
                print(error)
                return
            }
            UserDefaults.standard.set(verificationID, forKey: "authVerificationID")
        }
    }

    static func verify(verificationCode: String?) {
        guard let verificationID = UserDefaults.standard.string(forKey: "authVerificationID") else { return }
        if verificationCode != nil {
            let credential = PhoneAuthProvider.provider().credential(
                withVerificationID: verificationID,
                verificationCode: verificationCode!)

            Auth.auth().signIn(with: credential) { (user, error) in
                if let error = error {
                    print(error)
                    return
                }
            }
        } else {
            print("No verification code")
        }
    }

}

This is what the console prints out:

Error Domain=FIRAuthErrorDomain Code=17048 "Invalid token." UserInfo={NSLocalizedDescription=Invalid token., error_name=INVALID_APP_CREDENTIAL}

What am I doing wrong? Thanks

Solution 1

I was also experiencing this problem. Checked the following:

• Correct bundle Id
• Correct Google-Info.plist
• Correct aps-environment value
• Correct APNS token type when calling auth.setAPNStoken (.unknown for auto detect)

Nothing helped until in Firebase app settings I uploaded the APNS authentication key (p8) instead of certificates - I used those certificates before for push notifications only and everything was working fine but for phone number notifications something went wrong.

Solution 2

It is most likely that you need to upload an .p8 Key file (I have an Enterprise account but same thing for developer)
In Apple Developer Account:

• All Keys
• Create New Key (+)
• Type in Global name for all of your apps
• Checkbox next to Apple Push Notifications service (APNs)
• Download your p8 file
• Upload to firebase dashboard

Solution 3

First regenerates APNS key and upload in firebase for cloud messaging

1) Import Firebase and FirebaseAuth

import Firebase
import FirebaseAuth

2) In didFinishLaunchingWithOptions Configure firebase.

FirebaseApp.configure()

3) Write these two func in AppDelegate.

  func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    let firebaseAuth = Auth.auth()
    firebaseAuth.setAPNSToken(deviceToken, type: AuthAPNSTokenType.prod)

}

func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
    let firebaseAuth = Auth.auth()
    if (firebaseAuth.canHandleNotification(userInfo)){
        print(userInfo)
        return
    }
}

Very Important note : uthAPNSTokenType set correctly for [sandbox / production] or set for common .unknown

In my case it was the apns token type that was wrong:

Auth.auth().setAPNSToken(deviceToken, type: AuthAPNSTokenType.prod)

should have been:

Auth.auth().setAPNSToken(deviceToken, type: AuthAPNSTokenType.sandbox)

Solution 4

In my case, the problem was an incorrect bundle id in the iOS app, in the firebase project settings (Project settings -> General -> Your apps).

I hope this helps anyone overlooking the same detail.

Solution 5

same problem questions have been before on SO. so would like to tell you setup all pre-require step before run code.

Pre-Require Steps:

• Register bundle id on Developer account and enable notifications for bundle id.

• Register same bundle id on firebase console setting page and create app, download Google-Info.plist file, make sure name should be same.

• Upload Push certificates on firebase console for sandbox as well as development.

• follow this below link for code implementation.

You should provide a proper code example of what you are trying to do.

[Jordan Tate]

thanks for the tip. i updated my post.

Possible duplicate of Firebase Auth using phone number returns an internal error

[Jay]

'Also, note that phone number sign-in requires a physical device and won't work on a simulator.' If that's not the issue, did you enable phone number authentication in your console?

[Guig]

For me it was that I had not correctly uploaded the APN key to Firebase

[Fakhruddin Abdi]

How did you fix it @JordanTate ?

[Anil Gupta]

I was also missing the APNs .p12 file in Firebase console. Once I Uploaded the .p12 then it worked.

[Fakhruddin Abdi]

Do you mean .p8 @AnilGupta, because i couldn't find adding .p12 APN anywhere

[Fakhruddin Abdi]

@algrid Where aps-environment ?

[Dilip Tiwari]

hiii i need help

[Famic Tech]

Where do you upload the p12?!

[maxhawkins]

When I deleted my APNS key and re-uploaded it it worked. 🤬

[Mohit Kumar]

I was not allowed to replace APNS Certificate.But changing to sandbox worked for me.Thank you so much

[Govind Maheshwari]

i am face same issue in react native ios release build...after adding prod code in appdelegate.m its worked. thanks buddy

[Balaji Ks]

It worked for me. No need to build. It can be worked in all the release build also.

[M. A.]

This was my issue. I delete the /ios folder for some reason and after that I forgot to set the correct bundle id

[tate_xy]

Worked Like a charm

[matsbauer]

i really tried a lot, but the sandbox type worked, finally! Thanks

[Michał Dziwota]

Thanks! In my case, it was an incorrect Team ID. Perhaps App Store ID is not necessarily - I have it blank and it works anyway.
