Binance login without 2fa
One does not need to have two-factor authentication to log in to their Binance account. A simpler one-factor authentication is available as well.
There are, however, some limitations on what one can do with an account that does not have two-factor authentication. An account that uses two-factor authentication is also more secure against hackers than an unverified account.
If one does not intend to trade a very large amount of cryptocurrency, the restrictions of the unverified account are not likely to pose a problem. However, many smaller traders bother with the two-factor authentication for security reasons.
