...However something distracted me when creating account and didn't save file with written mnemonic phrases. My question is " Will i need these to send crypto to another wallet/binance ? "
First, do you still save the private key or keystore+password of your wallet? If yes, it is still no problem and you can back up your mnemonic phrase. Basically, there are several ways to access your imtoken wallet:
1. Using Private Key If you forgot or lost your PK, you can still access the wallet and then retrieve the PK again by loading it using your mnemonic phrase or Keystore +password.
2. Using the mnemonic phraseIf you lost your mnemonic phrase, you can still be able to access the wallet using your PK or keystore+password and then make a backup of your mnemonic code.
3. Using Keystore and passwordYou need to use these at once. Noted that you must save the password, if you lost your password, then you can't access using your Keystore. You can also still access the wallet using a private key or mnemonic phrase.
Special notes:
- As long as you still save and have private key/mnemonic phrase / keystore+password, you are still safe and can access, control, and manage your wallet. But it is better to save those all and make backup to ensure the security.
- If you lose one of them, you can still access, manage and control your wallet using the two others.
- It is important,
NEVER give or show your private key, mnemonic phrase, keystore+password to other people even they try to help you. Those are very secret.
- Losing all the data/information means that you lose your wallet.
