Your seed phrase is crucial for accessing your wallet. This article outlines the ways in which you could store it safely and securely.
First, please note that taking screenshots/photos of your seed phrase or storing it on your computer is extremely risky, as it makes it easily accessible to hackers and malware.
Having said that, here are some safer options:
Write it down on a piece of paper stored safely in or outside your house (for example, in a safety deposit box). You could also try splitting it – that is, storing the different parts in different secure locations
Purchase a steel plate or capsule. These can withstand extreme conditions such as high temperatures.
