Problem with login username in cart

[martin@.....cz]

Good day friends. I have a problem.

When the buyer has created an account on the site and enters the cart, his username stored in the browser is automatically inserted into the last field in the address. How do I prevent it? I set the last field of the phone number with a placeholder ... but it doesn't help

hello, the issue is caused by an extension in your browser - pls contact the developer of the extension which inserts the datas there.

you can alter placeholder or autocomplete rendering of the field with opc shopper fields section, but this won't fix the broken extension (usually Lastpass), there is no way to prevent Lastpass entering incorrect values directly. You may want to rename the field, so it doesn't think it's a username input.

best regards, stan
