Huntington Bank updated its mobile app Tuesday to let on-the-go customers check their balances without needing to enter in their user names and passwords. 

The Ohio Bank joins Bank of the West and Citigroup in letting customers access their balances without logging in. The enhancement is meant to let people access the data they most want quickly on a device with limited real estate. 

The update comes at a time when banks nationwide are striving to find quicker ways to authenticate consumers. Capital One, for example, lets customers access its mobile banking app by tracing a pattern on the device. U.S. Bank is piloting the use of voice authenticationon its mobile apps.
