The solution in this article is ineffective. Using IOS 14.2 on my iPad and iPhone. I have had to delete and recreate the mail account already because of certificate errors. Now the system keeps telling me that no password is provided. This is not a password error or an account settings error on my part as I am using the exact same information on my MacBook Pro which is still able to send and receive emails. I believe that the fact my MacBook can send and receive should be sufficient evidence that there is not a problem with my provider. This issue with failing to send and receive on my iOS devices popped up in the last 2 days and no matter how many times I delete and recreate the account, the message persists about no password provided. When I have provided an incorrect password, it tells me the password is incorrect. Here I have provided the password, yet it tells me it is not present.
