How to Log in to Amazon without Verification Code?

As a result of two-factor authentication, if your phone is stolen or lost, you may also lose the ability to log in to online sites like Amazon. The good news is that we've discovered a workaround for those of you who are having trouble logging in to log in to Amazon without verification code. Login Amazon Account without Verification Code A few alternative techniques to get into your Amazon account will be discussed before we get into the real account recovery process, which we'll cover in detail below. To be precise, there are two. Follow these procedures to log in to Amazon without a verification code. Your cursor over your name on the Amazon desktop site. Click on Hello, Your Name, and then Your Account. Click on Login & security. For two-step verification (2SV) settings, click Edit. Click Disable Two-Step Verification. Text or Call for An OTP If you lose your phone, you also lose access to the SIM card. To switch to a new SIM card, call your wireless service provider and request that your old one be disabled. A different phone number, such as one belonging to a member of your immediate family, may have been provided for you to use that number to log in to amazon without a verification code. Click on Didn’t Get The OTP The screen that appears when you sign up for an Amazon account and input your ID and password is called the Amazon 2FA page to log in to Amazon without Verification Code. Re-Enter Your Sign-in Credentials Amazon will display the last three digits of the backup phone number if added to the list. Using this number is as simple as logging in with a one-time password (OTP).  Step 1: Click on Send OTP and then Text or Call to send the code. Step 2: Enter the OTP you received through text or phone call to the backup phone number and click Sign In. You're now logged in. Step 3: Login and security are available under Amazon Account settings, which you can access at a later time. Two-factor authentication settings may require a new login.  Step 4: It's now time to update your authentication phone number or disable Two-Step Verification until you have a new phone and SIM card set up.  Step 5: To do this, click the Edit button below the Two-Step Verification settings. Locate A Reputable Device Don't ask for codes on this device; have a checkbox next to it when you connect to your Amazon account. If you've previously activated this option on another device, you won't have to enter the Authentication to log in to Amazon without Verification Code. Depending on where you work, it could be on a desktop or a laptop. It's well worth a look.  Recovering A Deleted Amazon Account Amazon's account recovery procedure is surprisingly simple. Using your Amazon password, log in to the account recovery page to provide verification information, such as a driver's license or voter ID. To submit the document, you can choose to upload it as a document, a PDF, or an image to log in to Amazon without Verification Code.  Make Your Account Future-Proof There are several ways to regain access to your account, but none of them are foolproof. A trusted device may not be available, or your account recovery process may be rejected. There are no promises.  Authentication from Two Phones In contrast to many other sites, Amazon allows you to add numerous authentication apps simultaneously, and all of the codes will function. As a result, using two phones for Authentication will make to login amazon without a verification code on another device considerably simpler. Step 1: Open Amazon. Select Account & Lists. Pick Your Account from the drop-down menu to add Authentication. Step 2: To access the security settings, select Login & Security and input your Amazon account password. Step 3: Complete the two-step verification process and click on the Edit button next to Two-Step Verification Settings to make changes. Step 4: Add a new app next to the authenticator app by clicking on Add new app. Step 5: Authentication is now complete.  Step 6: To verify, enter the one-time password (OTP) created by the app. Step 7: This method works with any phone in your family, including those with whom you have a shared Amazon Prime membership Assemble Extra Phone Number Adding numerous phone numbers for Authentication is just like adding a new authenticator app. 1: When you arrive at the Two-Step Verification page, select add a new phone. 2: Continue by entering a new phone number here. 3: Now, when you check-in, you'll also be able to utilize this phone number to receive a text or voicemail. Conclusion If you only require a few pieces of paperwork to verify your account, it may not always be successful. Because of this, it is a good idea to enable a secondary authentication device and a trusted phone number. Make sure this doesn't happen again by taking the required precautions to log in to Amazon without a verification code.
