Many users found their tokens stolen after signing a malicious transaction from [a phishing email from OpenSea](https://www.testingcatalog.com/opensea-asks-users-to-migrate-existing-etherium-listings-to-a-new-smart-contract/). An OpenSea competitor [X2Y2](https://www.testingcatalog.com/a-new-x2y2-nft-marketplace-is-airdropping-its-tokens-to-opensea-users/), took immediate action by adding the anti-phishing feature.

There you can set any passphrase that will be added to every email from X2Y2 so you can ensure that it is valid. This option is available under the [notifications tab](https://x2y2.io/settings/notification?ref=testingcatalog.com) under the profile settings section.
