Method 1: Using Emergency Bypass (No PC Required)

This "trick" works on select Vivo devices with older firmware.

Steps:

1. Power ON your Vivo Y21A and check your FRP lock screen.
2. Tap on Emergency Call.
3. Vivo Test Menucode is ##5588## or you can also try this one 5588#*#.
4. If you see a prompt on the screen, follow it to turn off FRP.
5.  Switch the device off and on to set it up without a Google account verification.
6. Note: Try the code `*#5588#` if the first one isn't working or use it again with `*#*#5588#*#*`. 

Method 2: Using ADB with a PC (If USB Debugging Was Enabled)  

The ADB can be used to remove the FRP if USB Debugging had been enabled prior to the application of the lock.

Requirements: 

- A PC having ADB & Fastboot installed.

- USB cable.

Steps: 

1. **Access the Recovery Mode**  

•    - Turn off the phone power.  
•    - Keep pressing Power + Volume Down until the Vivo logo shows up.  
•    - After that, select Recovery Mode.

2. **Activate ADB Access**  

•    - Use Apply update from ADB in Recovery.  
•    - Connect the phone to the computer.  

3. Remove FRP through ADB  

•    - Click on Command Prompt (Admin) in the PC.  
•    - Enter:  
•      ```bash  
•      adb shell  
•      pm disable com.google.android.gms/.auth.frp.FrpActivity  

   - Restart the phone and finish setting up.

Method 3: Using FRP Bypass Tools, Mainly for Advanced Users.  

Should any of the previously described ways fail, there is the option of third-party tools such as the Octoplus FRP Tool or Unlock Tool, in which case you have to pay a premium for them.  

How to:  

1. Get a FRP bypass tool installed on your PC.
2. Put the Vivo Y21A into EDL Mode. This may require a test point.
3. Link the phone to the PC and flash a modified firmware to get through the FRP.  

*Caution*: Improper flashing of firmware's can lead to device bricking. So take necessary steps.
