The newly introduced passphrase length of 6 words means that the passphrase generator is useless for about 50% of the sites I use which have a maximum password character limit.
For some sites I use passwords with random characters but where I am prevented from installing the browser extension, being able to type a Passphrase means I am less likely to make a mistake.
Please revert the decision to default to 6 words and/or remove the restriction on users changing the number of words to fewer than 6. By all means caveat the change with warnings but you have worsened the user experience by requiring the user to delete extraneous words to meet legacy character limits.
Do vote for the feature request, but FYI, the change in question is already being reverted. The feature request is still relevant, because there is still some arbitrariness in the default limits and in the recommended values.
I moved your comment into a different thread, as it was not relevant to the thread where you had posted it.
As you can see from the comments above, this new behavior was an intentional change made by Bitwarden (not a bug), but it will be removed in the next release.
