I am using a password manager to generate safe, long, unique passwords. Because those passwords tend to be 20-characters long they are a pain to type, but they are not even intended to be typed, merely cut and paste.

Now, some webapps (e.g. PayPal when creating a new user) actively intercept paste operation from the JS in the page in order to prevent me from actually pasting my nicely generated password.

How can I temporarily prevent the JS in Chrome to intercept the paste operation, making it appears as if I had entered sequentially, albeit very fast, the content of buffer?
