have been using trust wallet for years now , and it's been safe for me over the years . although , i heard on some security breaches but i think they reimburse users
and also, trust Wallet mobile apps and extension are security audited and pen-tested by the internal security of the trust wallet as well as external 3rd party security auditors too besides, its a non custodial wallet so its managed by you , just ensure that you are vigilant by not downloading malwares
