Hi Yug Faa,

as far as I know there is no addon available for odoo to limit the login attempts. I would recommend to protect your odoo as soon as it is available over the internet with fail2ban. This is very easy and I wrote a short explanation (unfortunately on german) on the following page:

https://www.ionas-server.com/blog/fail2ban-schutz-vor-brute-force-angriffen/

It is very easy to protect odoo with fail2ban.

1) find the log file that logs the login attempts. I use nginx and I told nginx to write everything to a log file: access_log /var/log/nginx/odoo-access.log;

2) create a filter

3) activate the filter

4) if you have a static ip: use the possibility to "ignoreIP" your own ip.

5) restart fail2ban

If you have any questions. Please let me know.

Christoph
