Every single time the OTP sent to my phone is “incorrect.” How is this possible with a billion dollar company? Even a broken watch is right twice a day. Pull it together Amazon.
First, you should not use SMS for OTP. Get an authentication app. Security experts state that the texts are bad. I only use it as a backup. Open my phone and sign in.
We only OTP maybe once a month. Not really a problem and I have seen posts on this forum, where they start getting a ton of OTP when they were not requesting it. This saved someones account.
The authentication app is more secure. Are you using the Seller app from Amazon and checking the box to not ask?
