Use a strong password. Password strength and rules for what the password must contain are shown while you create it. Only password of sufficient strength can be used. We recommend using a password with the highest strength shown by mojeID.

Protect your password from third parties and store it safely. If you use a password manager, ensure that its owner is trustworthy.

If you have even the slightest suspicion that your password has been compromised, change it immediately here.


If you use two-factor authentication, keep the device secure (mobile device, security key, etc.) from third parties. Always keep the software in your mobile device up to date.

We recommend using security keys with FIDO2 standard, ideally with Level 1 certification or higher. List of certified security keys with the option to sort them by security level can be found here.
