Some websites and apps offer two-factor authentication (also known as multifactor authentication), which helps prevent other people from accessing your accounts even if they know your passwords. Passwords are the first authentication factor, and temporary, one-time verification codes are commonly a second factor. iPhone can automatically generate these verification codes without your reliance on SMS messages or additional apps.
Set up automatic verification codes for a website or app by scanning a QR code
If you have another device with a screen, like a computer or iPad, you can use it to display a QR code from a website or app, then use the iPhone camera to scan the code.
On your other device, sign in to the area of the website or app where you manage your account, then select options to enable two-factor authentication and an authenticator app.
A QR code appears to help you set up an authenticator app.
On iPhone, select your account for the website or app.
A verification code appears below the User Name and Password fields.
On your other device, enter the verification code that appears on your iPhone.
Set up automatic verification codes for a website or app by entering a setup key
If you can’t scan a QR code from another screen, you can manually enter a setup key.

Choose the option to manually use a setup key (or setup code or similar), then select and copy the setup key.
Go to Settings > Passwords, then select your account for the website or app.

Use a verification code on a website or in an app
Sign in to the website or app.
If prompted, select the option to use an authenticator app.
When asked for a verification code, tap the suggestion that appears above the keyboard.
If no suggestion appears, go to Settings > Passwords, select your account for the website or app, tap the verification code, then tap Copy Verification Code. Return to the website or app, then paste the verification code into the field.
Automatically delete one-time verification codes
One-time verification codes are filled in automatically, so you don’t need to leave the app or website you’re signing into. You can choose to automatically delete the verification codes after entering them with Autofill, or keep them.
Go to Settings, then tap Passwords.
Tap Password Options, then turn Clean Up Automatically on or off.
Go to Settings > Passwords, then select your account for the website or app. Tap Set Up Verification Code, then tap Enter Setup Key. Tap the Setup Key field, tap Paste, then tap OK. Tap the Verification Code field, then tap Copy Verification Code.
In your Android Settings page, tap on System and then Advanced. From the Advanced System Settings page, select Autofill. Tap on SMS Verification Code Autofill. Enable Autofill SMS Verification Code and then select your message provider.
Go to Settings > Password > AutoFill Passwords and ensure it's turned on. Restart Your iPhone: Sometimes, a simple restart can solve the problem. Press and hold the Power button, then slide to power off. Wait a moment and turn it back on.
On your iPhone go to Settings > [your name] > Sign-In & Security. Tap Turn On Two-Factor Authentication, then tap Continue. Enter a trusted phone number (the number you'll use to receive verification codes), then tap Next. A verification code is sent to your trusted phone number.
one-time-code is a valid autocomplete -value, and with a few lines of JS, it let's you fill out the field from a text-message (sms). More often, it's called OTP, though.
With the SMS Retriever API, you can perform SMS-based user verification in your Android app automatically, without requiring the user to manually type verification codes, and without requiring any extra app permissions.
Reboot your Android. Restarting your device can resolve a lot of temporary technical hiccups, including network connection errors, so it's always worth a try. Check your phone number. Try sending the verification text again, and this time pay special attention to make sure you provided the correct phone number.
There could be several reasons why you're not receiving these texts, such as network issues, incorrect phone number, or a problem with your phone carrier.
Users can enable or disable autofill as well as change the autofill service by navigating to Settings > System > Languages & input > Advanced > Input assistance > Autofill service.
