There is no built in support for this, but you may be able to modify your theme to allow for this functionality using javascript.

Here is a relatively simple example online - https://www.w3schools.com/howto/howto_js_toggle_password.asp - that should be helpful.

Passwords don’t expire unless you configure the expiration (max age) in the password policy. So by default your password will never expire.

You can implement any password hashing scheme as a plugin and load it into FusionAuth. Then you simply migrate the user using new scheme. There is a tutorial on that matter in the docs.

If you want to use the breached password detection feature, then that check will be applied for any new account registrations.

You could always disable the breached password detection feature.

Sorry, I don't have a better answer for you.

Our validation takes in inverse approach. The setting is actually to require a non-alphanumeric character. So any character that is not alphabetic, or a digit, will satisfy this requirement.

There is not a fixed set of symbols as this would reduce the password entropy, which is generally a bad idea.

Actually, as of when I write this post, we have two license keys available for anyone with a paid edition. One is a prod license and the other is a non prod license. The latter is a good fit for testing, CI, etc.

Currently the only way to accomplish this will be to use the Import API, as you mentioned: https://fusionauth.io/docs/v1/tech/apis/users#import-users

We do have an open feature request to allow hashes to be provided on the User API, which I think would be what you're looking for: https://github.com/FusionAuth/fusionauth-issues/issues/348

Feel free to upvote that issue.

There are no inherent limitations of password stored in FusionAuth.

You can, however, choose to limit passwords using password rules. You can set these up at the Tenant level; look for the "Password settings" section under the "Password" tab.

You set these at the tenant level.

Home / Settings /Tenants / Edit in the admin UI.

You can also use the API or a kickstart file to set these.
