Can I set login attempts limit when web console admin login?

Hi.

for examples, When admin login try 5th failed, admin’s login try will lock.

and unlock other way on right id/pwd

I want to set this option, but I can’t find.

Hi Rasol,
Currently, that option is not available natively with CB server, here’s a link with option for managing users and user passwords via the CB CLI:
https://docs.couchbase.com/server/current/cli/cbcli/couchbase-cli-setting-password-policy.html and
https://docs.couchbase.com/server/current/cli/cbcli/couchbase-cli-user-change-password.html
Gives you the ability to set min-length, uppercase, lowercase, digit, and special-char, and, the 2nd link to change password for a user, for what you are looking for, you may need to integrate user management to something like LDAP:
https://docs.couchbase.com/server/current/manage/manage-security/configure-ldap.html#:~:text=The%20LDAP%20tab%20allows%20an,be%20assigned%20Couchbase-Server%20roles.
Hope this helps.
