I just wanted to use blockchain.info for temp use
Just don't use it if you'll thinking to put big amount of bitcoins there for good. Don't use it as a storehouse, use other wallets that are even safer than bc.info. You can try greenaddress if you can't avail a hardware wallet.
As many others suggested, it is not recommended to use online wallets. But if you prefer web wallets over software or hardware ones, blockchain.info looks the best option in my opinion since it has lots of feature like for example the option to buy BTC and ETH directly from your wallet.
I'm using it because it's very handy and easy to use but it's only for small amount not with big amounts. Greenaddress is a good one which supports Segwit too.
