Be sure to backup your Seed Phrase/Secret Recovery Phrase in a secure place. As suggested above you can save it in a password manager, a bank vault, a safe deposit box, or you can always write it down and store it in multiple secret places (honestly this is the least safe option).
Most importantly never share your recovery phrase with anyone for any reason, not even Centric or MetaMask support. If you are putting together a will or other such preparations be sure to consider a secure location where this information can be found in the event of your death. If someone asks for your recovery phrase, they are most likely trying to scam you. Without this phrase, your funds can’t be recovered if your device is damaged or lost. Confirm that you’ve written them down on the next page.
Once uncovered you will go to a new window which will ask you to select your Secret Recovery Phrase in the order you received it, as you select them from the bottom options they will fill in the box above. Once all of the words have been selected in the order received, select the Confirm button.
