I analyzed the current set of blocked bugs:
* On shutterfly.com, the site limited the length of passwords and saved truncated password, but Chrome saved the generated password. Now the site uses “max-length” attribute, Chrome takes it into account. So, it is ok. 
* creditkarma.ca requires a special symbol. It is probably the most common failure. 
* Optional: do consider "pattern" attribute as well. Supporting all possible patterns may complicate password generator implementation. 

The plan is the following:
1. Add flag that indicates whether user edited generated password.
2. Check the sites where many edits happen. Are there problems with length, special symbols or something else?
(3) Optional: Collect more detailed data about edits (changed length, special symbols, etc.). 
4. Implement server-side processing of data collected at (1) and (3) and propagate the outcome to the client side.

We would like measure the number of edits of generated passwords. In M69, we introduce mechanism to adjust passwords based on sites' requirements. We need to see the difference.

Your change meets the bar and is auto-approved for M68. Please go ahead and merge the CL to branch 3440 manually. Please contact milestone owner if you have questions.
