I lost my trezor

I have just purchased a replacement model T… Originally I had a 12 word recovery phrase which I have not lost. I would like to add another 12 words to make it more secure. Can I do this? And a video to explain please?

Hi @Winston

You can choose the version of the recovery seed (meaning number of words) by using trezorctl commands.
It is an advanced feature for advanced users.
more info here:

Also please note that after you set this you will have to create new seed (that consists of 24 words) and transfer all the funds from your current wallet there.
It is not possible to just add the extra 12 words to already existing seed as all addresses are derived from such input (that will change).

Also, 128 bits of encryption (12 words) is considered safe enough so frankly there is no need.
