Nintendo: the right habits for a truly tough password

How well your Nintendo account holds up comes down, first and foremost, to a strong password. Ideally it stays exclusive to that service and never gets reused elsewhere. On Nintendo, the length starts at 8 characters, drawing on at least 2 different character families, while avoiding the same character more than 2 times back to back, up to a ceiling of 20 characters.

A realistic target sits around 16 characters: that is where strength and everyday convenience meet. No need to memorise any of this, the generator on this page enforces these criteria on its own. Rest assured: the key comes to life inside your own browser and is never transmitted or kept on any server.

On Nintendo, how many characters does a password need at the very least?

The floor set by Nintendo is 8 characters, though reaching 16 leaves your account far better defended.
