Visit https://phantom.app/download and select your browser type. Follow steps in your respective extension store to add Phantom to your browser. After installing, you should see Phantom start up in a new tab:
If you are a brand new Solana user, select "Create New Wallet". If you are an existing Solana user coming from sollet, you can follow steps here to migrate your existing wallets to Phantom.
Store your "Secret Recovery Phrase" in a safe and secure location, it is the only way to recover your wallet. At no point will a member of the Phantom team ever ask you for this phrase. Whoever has access to this phrase has access to your funds. Note: We now have an integration with 1Password for safe storage of your secret recovery phrase.
DO NOT share your Secret Recovery Phrase with anyone! If someone has access to your secret phrase, they will have access to your wallet. Phantom support will NEVER ask you for your secret phrase or your private key.
Look for the Phantom icon in your browser's toolbar.
If you are using Chrome, it will be in the top right hand side of your browser. If you don't see it look for a "puzzle piece" icon and click on it to access a list of installed extensions. There you should find Phantom, click on the "pin icon" to make it easier to find in the future.
