“92 minutes of applauses”

And when I use a passphrase that my password manager generated, the sign up form called it “weak”.

Then respectfully it might be your fault, but I don’t know the metrics for which Lemmy rate the passwords, you can also use this other estimator, download the local version of course:
https://github.com/dropbox/zxcvbn

I for instance used a simple setting:

and got:

;;75.cupcake.manly.argument.53%%

testing it on https://lowe.github.io/tryzxcvbn/

Lemmy although gives it a “medium” quality rating to the password, so I guess it must estimate it differently

Requiring a 10 character password with additional character conditions is going to turn a lot of possible new users OFF. It should be 6 characters, with no conditions.

I gather that is not your case and I see what you mean if I think about my parents for instance, but objectively I can only think that a 6 characters password with no restrictions (e.g. 123456) might have been “okeish” and yet still object of jokes 20 years ago, but now it shouldn’t absolutely be passed as a norm anyway close to “adeguate”, users need to be correctly educated on their own security awareness in general, but also especially here because the it is very likely that the instance where the user account is registered to will not have any paid customer service around to solve their users issues with account security breaches because of their weak passwords.

So regarding passwords for the casual as for the expert user once and for all the xkcd comics stripe on passwords:

and here is a couple of handy online and downloadable generators inspired from that comics stripe:

https://xkpasswd.net/s/

But also learn to use password managers! Which also come often with their own handy password generators btw. The gist of it is that you need to remember only one password for the manger, and in turn it is going to remember and service for you your credentials for all your accounts. .

For instance for the average casual user Bitwarden should more than suffice, it is free, has a freely managed remote service, apps for mobile and extensions for the browsers, it is open source and has been audited: https://bitwarden.com/

I perfectly know that is a an uphill process, I can see that with my parents, but I also like to think that maybe if something I tell them about how to manage their passwords is able to stick in their mind then one day it might save them from being robbed online for always using the same few charters password everywhere for every effing website.
