Firebase 更新电子邮件和电话号码。 “此操作很敏感，需要最近的身份验证。” updateEmail ios swift 上的错误

Question

I have a profile page in my app, where user can update phone number and email, so while updating email i am getting this error "this operation is sensitive and requires recent authentication"

Here is my code for update email

Auth.auth().currentUser?.updateEmail(to: self.txtEmail.text ?? "", completion: { (err) in
                            
                        })

So i decided to use updatePhoneNumber method so it will show otp prompt and so phone number update is done in that method and we can consider it at recent login, so in completion block of updatePhoennumber method i am using updateemail method but still getting same error is there any other solution? we are not creating account with password so i don't have password for that email. So please let me know if i can do both operation in single verification. Below is my code

    let credential = PhoneAuthProvider.provider().credential(
                withVerificationID: verificationId,
                verificationCode: verificationCode)
            if let user = Auth.auth().currentUser {
                
                user.updatePhoneNumber(credential) { (err) in
                    if let error = err {
                        
                        return
                    } else {

Auth.auth().currentUser?.updateEmail(to: self.txtEmail.text ?? "", completion: { (err) in
                                
                            })}

Please let me know if there is any other way to achieve it.

Answer 1

You must re-authenticate the user using reauthenticateWithCredential:completion: on the FIRUser object. First, obtain the user's credentials (here are two examples):

let emailCredential = EmailAuthProvider.credential(withEmail: "some@email.com", password: "somePassword")
let facebookCredential = FacebookAuthProvider.credential(withAccessToken: "someToken")
// or other

And then pass it into the reauthenticate method:

Auth.auth().currentUser?.reauthenticate(with: emailCredential, completion: { (result, error) in
    // go from here
})
