If you Log in through Mistertango account and do not remember your password go to Mistertango log in page and under all fields you will find a link "Forgot password? Create new".

If you are using Mistertango account and still remember your password, you can change it by Logging in and under settings searching for "Change password" section. Enter your old password and a new one. Once you are done, you should receive an email with a confirmation about your changed password.

If you Log in through BTC-Exchange form (only users registered before 2017) all links are equivalent.
