If you enter the wrong password three times in a row while logging into your Pipedrive account, you will be locked out of your account. This is to ensure that your login process is protected against external threats. 

When you are locked out, you will be automatically sent an email to unlock your account. Once you unlock your account through the email, you can log into your account using your email and password again. If you don't remember your password, we recommend resetting your password. 

Security Dashboard

If you are on the Professional or Enterprise plans, you will be able to see login attempts in the Security Dashboard. To see when users have failed to login three times in a row, go to your Audit log tab.
