Safari Password Generator - automation

Hi all,

I've recently found some time to update passwords and figured its time to begin using Safari's built in Strong Password Generator to help protect my accounts.

The issue I have now is whether or not I line by line, begin updating all the passwords manually or if there is some way that I can auto-generate/populate the info in bulk or at least a faster method.

in my mind it seems like the later might be impossible without a third party password app because the Safari Password Vault needs to open the unique web address tied to the old password in order to update with the Strong Password functionality.

I have a few hundred to update so going line by line doesn't appeal to me at the moment. I've also thought about deleting all my stored passwords in Safari and just update them with the built in Strong Password function the next time I visit that particular site.

any suggestions on what the best practice for this would be?

thanks.
